Calculate the evaporation rate from an open water source, if the net radiation is 300 W/m² and the air temperature is 30° C. Assume value of zero for sensible heat, ground heat flux, heat stored in water body and advected energy. The density of water at 30° C=996 kg/m³. [Hint: Calculate latent heat of vapourisation L by the formula: L = 2501 – 2.37 T (kJ/kg), where T= temperature in °C.]
