(a) Estimate the depth of evaporation (in mm units) that can be expected to occur over a 24-hour period from a location under the following conditions: Available Energy = 600 W/m² Bowen Ratio = 0.4 You can assume the latent heat of vaporisation equals 2.5MJ/kg and the density of water equals 1000kg/m³. E = mm (b) When the Bowen ratio is less than 1, does the air above the water surface get warmer?
