its been a long time

holy jebus! over a year of neglect. maybe ill start n use this as a CF tracker for the transition into the new year and beyond…

arrhenius and the mayor…

the following article was published in ASHRAE Journal, May 2009.

By Joseph W. Lstiburek, Ph.D., P.Eng., Fellow ASHRAE

In a strange world with strange connections, one of the strangest connections of all exists among Jan Laverty Jones, John Rushworth Jellicoe, British dreadnoughts, German U-boats, and Svante Arrhenius.

Our story starts with a politician taking a shower in a new home in Las Vegas in the mid 1990s and ends with tens of thousands of houses with leaks and litigation. Our story takes a detour to the Great War (This was before we started numbering them. The first World War was thought to be the war to end all wars.) and one of the most famous naval engagements that almost didn’t take place and an underappreciated and much maligned national hero.  Along the way we become reacquainted with one of the greatest minds of all time – so great that the physicists and chemists both claim him as one of their own.

Jan Laverty Jones buys a new house in Las Vegas and is incensed that it takes five minutes for hot water to get to her shower.  She becomes furious when the builder says that he is not responsible and that’s the way it is.  Unlike most new homeowners with a grudge, she happens to be the mayor (Photo 1).  In a move that would make Boris Yeltsin proud, she decrees that all new houses must have hot water recirculation systems.  OK, it wasn’t a decree. It was a bylaw change.  But, you get the idea.  Never mind the energy implications of this decision.  This was the 1990s. Who cared about energy back then?  The implications of this decision haunt Vegas homeowners and home builders to this day.

What is the big deal about hot water recirculation systems? They have been around a long time. We know how they work. We know about the energy penalties. Well, Las Vegas is different, as we all know. But, the difference I am referring to is the water, not the other stuff. The water in Las Vegas, when coupled with hot water recirculation systems and the type of plumbing system that became common in the home building industry around then, makes for an interesting study of physics, chemistry, and unintended consequences.

Las Vegas has lots of sulfates and carbonates and a high pH in its water, along with lots of chlorides and fluoridates. The sulfates and carbonates and high pH come from nature; the chlorides and fluoridates come courtesy of the Las Vegas water department. And, for reasons not well-understood, Las Vegas water has lots of dissolved oxygen.

None of this is a surprise to folks who know and love water. It does not seem to be a problem with the folks living there since gangster Bugsy Siegel kicked Las Vegas into the big time in the late 1940s. But it has been, and continues to be, a huge problem with hot water heaters. Hot water heaters in Las Vegas fail faster than almost anywhere else—often in only three to five years.

The hot water heaters fail from the precipitation of those pesky carbonates in the water. Now, other places also have lots of carbonates, but not lots of dissolved oxygen, and not lots of other neat stuff in the water as in Las Vegas. The precipitation of the carbonates is much faster in Las Vegas hot water heat­ers than elsewhere. This results in the sort of unintended consequences that leave your head spinning. The water heaters are, in essence, pretty effective water-purifying systems, which take dissolved minerals out of the water. The minerals of interest happen to be calcium and magnesium. Remember this for later.

The problem of failed hot water heaters in Las Vegas is simply accepted. You move to Las Vegas, and live with the fact that you must replace your hot water heater every couple of years. It is an­noying, but not a big deal. Everyone goes through it. The water heaters are all located in garages. They are easy to replace. There is no real collat­eral damage to worry about. Las Vegas lives with a system of disposable water heaters. Think of it as a “hot water tax” that is almost unique to Las Vegas.

Home builders, in their continuing efforts to reduce their costs and improve their production efficiencies, began to replace traditional copper-based piping systems with cross-linked poly­ethylene (PEX) water supply piping. PEX has a lot going for it. It does not corrode, is chlorine-resistant, it does not develop pinhole leaks, has fewer fittings, connections, and elbows. Did I mention the part about the fewer fittings, connections, and elbows? Home builders began to use PEX systems almost everywhere, including Las Vegas.

With PEX systems the fittings and couplings are almost universally brass. Brass, which is a metallurgist’s dream, is a magnificent alloy of copper and zinc. But to the British Grand Fleet and its commander John Rushworth Jellicoe (Photo 2), admiral and hero of the British Empire, brass is a nightmare.

Photo 2: Sir John Rushworth Jellicoe. British Grand Fleet Commander Admiral, hero of the British Empire. Trashed by his subordinate, Vice-Admiral Sir David Beatty, whose poor tactics resulted in severe losses to his own battlecruiser squadron. Jellicoe was maligned by the press at the time for not destroying the German fleet. In a bitter irony, Jellicoe was more respected by his adversaries than his own nation. Germany sent a contingent to his funeral, but pointedly did not provide a similar honor at Beatty's funeral. In a final twist to the saga, Beatty caught pneumonia at Jellicoe's funeral and died shortly afterward.

British dreadnoughts (Photo 3) used 70/30 brass tubes in their condensers. These brass tubes, 70% copper, 30% zinc, suffered from “dezincification,” which is a process where zinc is preferentially removed by corrosion.  Zinc is a highly reactive metal with a weak atomic bond. The process is referred to by old sea dogs as “condenseritis.” (The used steam from the engines is passed into salt-water cooled condensers, so that the feed water can be pumped back into the boilers. If the condensers leak, the salt water contaminates the feed water, affecting the generation of steam, damaging the turbines.)

Photo 3: The British battleship HMS Dreadnought. The Dreadnought so revolutionized naval power that an entire class of battleships was named after her.

Dezincification had more effect than German U-boats (Photo 4) and the Imperial German Navy’s High Seas Fleet in knocking British ships out of action during World War I.

Photo 4: German WWI U-boat Unterseeboot (undersea boat).

Because of condenseritis, Admiral Jellicoe almost didn’t steam out of Scapa Flow‡ to meet Vice-Admiral Scheer and their respective destinies at arguably the largest naval battle in history—the Battle of Jutland—the greatest clash of big-gun armored war­ships ever.

British metallurgists eventually solved the problem with adding arsenic, which produced “admiralty brass”. So, that was pretty much it for brass for about a half a century.

The problem of dezincification of brass water fittings was first identified in the 1950s.1 This type of dezincification is referred to as “meringue dezincification” where the corrosion product, zinc oxide residue, blocks the fitting (Photo 5). Although me­ringue dezincification was known since the 1950s, it was rare unless you had “aggressive water,” which is water with high levels of oxygen, chloride ion and sulfate content. Hello, Las Vegas. Guess what happens when we begin to see lots of brass fittings and couplings in Las Vegas?

Photo 5: Meringue dezincification. Note the corrosion product, zinc oxide residue, blocking the fitting.

This leads us to Svante Arrhenius (Photo 6). Heat is needed for most chemical reactions to occur. Arrhenius gave us the quantita­tive relationship that governs these reactions. This is a big deal. Activation energy is his baby. Maxwell-Boltzmann distributions, Gibbs free energy, and Planck’s constant all are intertwined with the Arrhenius equation. Engineers, being engineers, simplify the famous equation: for most chemical reactions the rate doubles for every 10 K rise in temperature. Guess what recirculation systems do? They make the hot water side of the piping systems hot all the time. Guess what this does to the rate of dezincification? Svante Arrhenius meet Jan Laverty Jones.

Photo 6: Svante Arrhenius. The boy from Vik, Sweden, writes a doctroal dissertation that gets the thumbs down treatment from the establishment at the Physical Institute of the Swedish Academy of Sciences. He has the last laugh when the work gets him the Nobel Prize in Chemistry in 1903. He still gets no respect today. He is the father of the Greenhouse effect, nto Al Gore. Arrhenius said this more than one hundred years ago, "If the quantity of cabonic acid increases in geometric progression, the augmentation of teh temperature will increase in nearly arithmetic progression."

Most of the new houses in Las Vegas with PEX piping are undergoing repairs and the associated litigation is a nightmare for everyone. In new Las Vegas homes, the damage never ap­pears on the cold side. Arrhenius again.

Las Vegas gives us some interesting twists. Remember earlier when I mentioned calcium and magnesium? These minerals typically form scale on brass fittings, protecting them from dezincification. Guess what? The water heaters take them out of the water accelerat­ing the process. Even more interesting, the elevated pH of Las Vegas water keeps the zinc oxide corrosion product at the fittings, blocking the water flow. So the meringue doesn’t get flushed out of the system.

So what to do? Take the zinc out of the brass. Of course, you can’t take it all out because then we wouldn’t have brass anymore. We would have copper. Unfortunately, we can’t use copper because it is not as strong as brass. The good news is that we have different types of brass. The most common type is “yellow brass,” which is 35% zinc. It is the problem child. Remember: yellow is bad. Another type of brass is “red brass,” which is less than 15% zinc. Red brass seems to work. Remember: red is good.

The couplings are the easy part. The trouble is that it is dif­ficult to find all red brass fixtures and faucets. And, when you do find them, not everyone likes the way they “look.” We don’t seem to have a lot of “designer red brass fixtures and faucets.” Do you want to look good, but leak?

What about the casinos? We know about new homes, but what about the important stuff in Las Vegas? Well, the casinos treat their water, have copper piping and regularly replace their fixtures. They consider their regular fixture replacement much the way homeowners consider their regular hot water heater replacement.

What else can you do? Well, you can move to Phoenix.  Why?  Well, by the time you get downstream on the Colorado River most of the problem disappears. So once again, pretty much what happens in Vegas stays in Vegas. So, is this the mayor’s fault? It’s an interesting question. You can make recirculation systems work with the right stuff even with bad water. But, as they say in this business—who knew?

good times…

what you know about ALOHA?…

“Aloha spirit is a coordination of mind and heart. It is within the individual, it brings you down to yourself. You must think and emote good feelings to others.”

A Translation of ALOHA, Letter by Letter

A stands for akahai, meaning ‘kindness, ‘ to be expressed with tenderness.

L stands for lokahi, meaning ‘unity, ‘ to be expressed with harmony.

O stands for ‘olu’olu, meaning ‘agreeable, ‘ to be expressed with pleasantness.

H stands for ha’aha’a, meaning ‘humility, ‘ to be expressed with modesty.

A stands for ahonui, meaning ‘patience, ‘ to be expressed with perseverance.

“These are the traits of character that express the charm, warmth, and sincerity of Hawaiians. It was the working philosophy of my ancestors.”

-Pilahi Paki

Pilahi Paki believed every word has power. That was the foundation of her teaching. Whether you’re talking or singing, she would say, ‘you speak clearly, you show respect for the language, you enunciate, and you choose your words with care, because they have an effect far beyond what you can hear.’

Mr. Kamaka…

Mr. Kamaka lived alone on the Windward side of O’ahu, known to all as Kahalu’u.

He wanted to dig his kalo patch, but it was very hard work because the ground was too hard.  His only son, Kimo, who used to help him, was in Halawa prison.  The old man wrote a letter to Kimo and explained his predicament.

Dear Kimo,
I am feeling  pretty bad because it looks like I won’t be able to plant my kalo patch this year.  I’m just getting too old to be digging up this hard soil.  I know if you were here you would be happy to dig the patch for me and it wouldn’t be a problem.
Love, Dad

A few days later he received a letter from his son…

Dear Dad,
No dig up the dirt in the kalo patch.  That’s where I buried the bodies.
Love, Kimo

At 4 A.M. the next morning, FBI agents and local police arrived and an army of men dug up the entire area without finding any bodies.  They apologized to the old man and left.

Later that same week Mr. Kamaka received another letter from Kimo.

Dear Dad,
You can go ahead and plant your kalo now.  That’s the best I could do under the circumstances.  Take care of the kalo.
Love you, Kimo

3 minute management course…

Lesson 1:

A man is getting into the shower just as his wife is finishing up her shower, when the doorbell rings. The wife quickly wraps herself in a towel and runs downstairs.

When she opens the door, there stands Bob, the next-door neighbor. Before she says a word, Bob says, ‘I’ll give you $800 to drop that towel.’ After thinking for a moment, the woman drops her towel and stands naked in front of Bob.

After a few seconds, Bob hands her $800 and leaves.

The woman wraps back up in the towel and goes back upstairs.

When she gets to the bathroom, her husband asks, ‘Who was that?’

‘It was Bob the next door neighbor,’ she replies.

‘Great!’ te husband says, ‘did he say anything about the $800 he owes me?’

Moral of the story:

If you share critical information pertaining to credit and risk with your shareholders in time, you may be in a position to prevent avoidable exposure.

Lesson 2:

A priest offered a nun a lift.

She got in and crossed her legs, forcing her gown to reveal a leg. The priest nearly had an accident.

After controlling the car , he stealthily slid his hand up her leg.

The nun said, ‘Father, remember Psalm 129?’ The priest removed his hand.

But, changing gears, he let his hand slide up her leg again.

The nun once again said, ‘Father, remember Psalm 129?’

The priest apologized ‘Sorry sister but the flesh is weak.’

Arriving at the convent, the nun sighed heavily and went on her way.

On his arrival at the church, the priest rushed to look up Psalm 129.

It said, ‘Go forth and seek, further up, you will find glory.’

Moral of the story:

If you are not well informed in your job, you might miss a great opportunity

Lesson 3:

A sales rep, an administration clerk, and the manager are walking to lunch when they find an antique oil lamp. They rub it and a Genie comes out.

The Genie says, ‘I’ll give each of you just one wish.’

‘Me first! Me first!’ says the admin clerk. ‘I want to be in the Bahamas , driving a speedboat, withut a care in the world.’

Puff! She’s gone.

‘ Me next! Me next!’ says the sales rep. ‘I want to be in Hawaii , relaxing on the beach with my personal masseuse, an endless supply of Pina Coladas and the love of my life.’

Puff! He’s gone.

‘OK, you’re up,’ the Genie says to the manager. The manager says, ‘I want those two back in the office after lunch.’

Moral of the story:

Always let your boss have the first say.

Lesson 4:

An eagle was sitting on a tree resting, doing nothing.

A small rabbit saw the eagle and asked him, ‘Can I also sit like you and do nothing?’

The eagle answered: ‘Sure, why not.’

So, the rabbit sat on the ground below the eagle and rested. All of a sudden, a fox appeared, jumped on the rabbit and ate it.

Moral of the story:

To be sitting and doing nothing, you must be sitting very, very high up .

Lesson 5:

A turkey was chatting with a bull. ‘I would love to be able to get to th top of that tree,’ sighed the turkey, ‘but I haven’t got the energy.’

‘Well, why don’t you nibble on some of my droppings?’ replied the bull. They’re packed with nutrients.’

The turkey pecked at a lump of dung, and found it actually gave him enough strength to reach the lowest branch of the tree. The next day, after eating some more dung, he reached the second branch. Finally after a fourth night, the turkey was proudly perched at the top o f the tree.

He was promptly spotted by a farmer, who shot him out of the tree.

Moral of the story: Bull Shit might get you to the top, but it won’t keep you there .

Lesson 6:

A little bird was flying south for the winter. It was so cold the bird froze and fell to the ground into a large field. While he was lying there, a cow came by and dropped some dung on him.

As the frozen bird lay there in the pile of cow dung, he began to realize how warm he was. The dung was actually thawing him out! He lay there all warm and happy, and soon began to sing for joy.

A passing cat heard the bird singing and came to investigate. Following the sound, the cat discovered the bird under the pile of cow dung, and promptly dug him out and ate him.

Moral of the story:

(1) Not everyone who shits on you is your enemy .

(2) Not everyone who gets you out of shit is your friend.

(3) And when you’re in deep shit, it’s best to keep your mouth shut!

This ends the 3-minute management course.

float da lanterns…

the annual Latern Floating Festival put on by Shinnyo-en Hawaii was this past memorial day. we were told that it wasnt going to be as large as the previous years (each year that ive gone its gotten bigger and bigger) because the church wasnt flying down as many Japanese from Japan because of H1N1…

although as you can see from the pictures, its was still packed…

each year they add something; they make the ceremony more open to more and more people, even those that arent religious.  this year they had more representatives from the Christian religions partake in the ceremony, plus they had a fuckin awesome trumpeter play a couple of songs/solos. dude was mean… 

we stood in line for this for at least 30 minutes, sweating our asses off.

kimono lady. she was hardcore. even had da slippahs on.

if you look closely, get a double hulled canoe with red sails.

20,000 people.

and another 20,000.

kimono lady again, with couple braddahs.

these kids made some for their dad and grandparents.

dana said that one was for a 13 year old girl, probably the guy’s daughter or sister.

the mad rush after.
