Evaporation calculation
(OP)
I'd like to be able to calculate evaporation rates for a settlement pond in an arid environment.
Does anyone have an excel calculation sheet?

The evaporation rate is influenced by
1) Temperature of the water at the air-water surface.
2) Humidity of the air.
3) Area of the air-water surface.
4) Air temperature.
5) Water currents that convect heat through the water depths.
6) Wastewater parameters.
7) Airflow rate past the water-air surface.
All of these paremeters are continuously changing so I is difficult to come up with an "evaporation rate".

Do you have access in your office to a Mechanical Engineer who may be able to pull up a Heat Transfer Text?

Unfortunately I don't have a Mech Eng at hand. I'll chase up the avenues and hopefully it will work out!

As well as this site that looks like it might help:

Here in the central San Joaquin Valley of California, our evaporation rates are not much less than gbam mentioned for Arizona. My swimming pool seems to evaporate about 0.5" to 0.75" per day in the hottest parts of the summer.
