For Cairo, Egypt, in July, average net radiation is 185 W/m2, air temperature 28.5°C, relative humidity 55 percent, and wind speed 2.7 m/s at height 2 m. Calculate the open water evaporation rate in millimeters per day using the energy method (E,), the aerodynamic method (Ea), the combination method, and the Priestley-Taylor method. Assume standard atmospheric pressure (101.3 kPa) and Zo-0.03 cm.
