Pond evaporation rate formula
WebDec 1, 1977 · The Penman formula for the evaporation rate from a lake is simplified to the following: E 0 = 700 T m / (100 − A) + 15 (T − T d) (80 − T) (mm day − 1) where T m = T + 0.006h, h is the elevation (metres), T is the mean temperature, A is the latitude (degrees) and T d is the mean dew-point. Values given by this formula typically differ from measured … WebDec 14, 2024 · Evaporation rates. 2 years ago. Updated. You can expect 1/2% - 1% of the total gallons per hour, per day to be lost to evaporation. For example: 3,000 GPH pump. 1/2% = 15gallons/day. 1% = 30gallons/day. Make sure to estimate the flow rate after head pressure loss, 3,000 GPH pump may only supply 2,500 GPH or less, this will make a …
