Having mentally undressed all the attractive girls sunbathing poolside (most are almost naked anyway), my mind wandered to the conundrum why the large pool's water is cooler than the shallow childrens pool. The pools lose energy (heat) by evaporating water, and the surface/mass ratio is higher in the shallow pool, so it should be cooler. Yet the opposite is true. The shallow children's pool is warmer and stinks of piss. May the heat contribution of the urine (36 degrees Celsius) cause the temperature paradox?
Yes. In the early morning, after a night of irradiating long wave energy and no hot piss additions, the shallow pool is cooler than the deep one. Yet around 0900 AM the relation reverses itself, and the children's pool becomes a warm nitrification reactor. Also the fact that the deep pool's volume is about 800 cu.m. vs 50 cu m of the children's pool affects the rate of temperature change. Next time I'll calculate the denitrication rate at different chlorine concentrations.

So a small shallow pond should be cooler than the sea?
K
In the morning, yes.
Perfect.

I learned to swim in a pool at 24 and immediately quit-all the mucus-looking shit floating around in there creeps me out. A lake, ocean or river, on the other hand, is fine, though I suppose there is plenty of shit in there too.
If you see stuff floating in a pool it means they are not respecting the parameters.
Water has to be permanently recirculated and filtered. And due to treatment it should pose absolutely no threat to human health.
If you see mucus floating it means they are probably bribing the sanitary authorities.
PS. I have done - the design part - ventilations for many interior pools.
I am still waiting for the denitrification taking place in pool enviroment oh mighty J. :)))))
I can not understand why a sewage engineer attacks us, the boys from HVAC.
We don't encounter nitrification - denitrification. It's the sewage boys job to take care of such lowly chemical processes. We deal with fresh air from Olympus itself.
:))))))))))))))))))
You went to a pool lately I believe.
I think that you did because I did it myself. And thought about it - kids pool versus adult one - because I had to enter with kids and noticed the difference.
Never thought to write about it though. That is why I read what you write and not the reverse.
What I do not understand is what were you doing in the kids pool?
Your children are not old enough if I understood correctly to have kids of their own but are old enough not no need the kids pool.
