The maximum and minimum temperature recorded at a Lake is 18°C and 15°C in February. The mean air temperature (T), pan evaporation (EP), wind speed (uz), relative humidity (RH), and net radiation (Rn) in a nearby weather station were found to be 23°C, 15 mm/day, 23 m/s, 47%, 20.54 MJ/m²/day, respectively. Estimate Lake evaporation (mm/day) using: (a) Pan Evaporation method, (b) Aerodynamic method, (c) Energy balance method, and (d) Penman method of combined aerodynamic and energy balance algorithm.
