Question
At a given location, the net radiation was 200 W/m2, the air temperature was 28°C, and the wind velocity at 2 m height was 3.0 m/s, relative humidity is 80%, roughness height is 0.1 cm. Use density of water = 1000 kg/m3 and psychrometric constant = 66.8 Pa/°C. Use energy balance method, aerodynamic method, and combined method to determine the evaporation rate (in mm/day).
