How to Calculate Rohwer‘s formula?
Rohwer‘s formula calculator uses Evaporation from water body (mm/day) =0.771*(1.465-0.00073*Atmospheric Pressure)*(0.44+0.0733*Mean Wind Velocity)*(Saturation Vapour Pressure at Water Surface-Vapour Pressure of Air) to calculate the Evaporation from water body (mm/day) , The Rohwer‘s formula Accounts for the effect of pressure in addition to the wind speed at a height of 0.6 m above free water surface (km/hr). Evaporation from water body (mm/day) and is denoted by E symbol.
