Evaporative losses from swimming pool

[wclark77]

Can anyone provide me with a reliable formular for calculating evaporation losses from an indoor swimming pool when I have the following information/data:

size of pool
pool temp
pool hall temp
pool hall % saturation
vapour pressure at pool surface
vapour pressure in pool hall
air velocity at pool surface

ideally I would like to be able to calculate the evaporative heat loss in W per m2.

Thanks

Many thanks. I had checked these pages out - the first was particularly useful. I had two issues though: firstly, it wasn't clear how they'd arrived at the evaporation coefficient. Secondly, it wasn't clear how I should calculate the humidity ratios. If anyone can point me in the right direction I'd be really grateful.
Thanks

and then select metric or US units and then click on "Evaporation from Non-boiling Liquid Pool".
