E = Ko*(es-ea)
This formula uses 4 Variables
Variables Used
Evaporation from Water Body - Evaporation from water body (mm/day) is the process by which liquid water from an open water surface is converted directly to water vapor.
Proportionality Constant - The proportionality constant represented by 'Ko' is the ratio between two directly proportional quantities which depends upon the characteristics of the aquifer and the area of the well.
Saturation Vapour Pressure - (Measured in Pascal) - Saturation Vapour Pressure at Water Surface (mm of mercury) is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature.
Actual Vapour Pressure - (Measured in Pascal) - Actual Vapour Pressure is the air in mm of mercury is the vapour pressure exerted by the water in the air.
STEP 1: Convert Input(s) to Base Unit
Proportionality Constant: 1.5 --> No Conversion Required
Saturation Vapour Pressure: 17.54 Millimeter Mercury (0 °C) --> 2338.46788 Pascal (Check conversion here)
Actual Vapour Pressure: 3 Millimeter Mercury (0 °C) --> 399.966 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
E = Ko*(es-ea) --> 1.5*(2338.46788-399.966)
Evaluating ... ...
E = 2907.75282
STEP 3: Convert Result to Output's Unit
2907.75282 --> No Conversion Required
FINAL ANSWER
2907.75282 2907.753 <-- Evaporation from Water Body

6 Evaporation Calculators

Rohwers formula (1931)
Go Lake Evaporation = 0.771*(1.465-0.00073*Atmospheric Pressure)*(0.44+0.0733*Mean Wind Velocity at Ground Level)*(Saturation Vapour Pressure-Actual Vapour Pressure)
Meyers formula (1915)
Go Lake Evaporation = Coefficient Accounting for Other Factors*(Saturation Vapour Pressure-Actual Vapour Pressure)*(1+Monthly Mean Wind Velocity/16)
Dalton-Type Equation
Go Lake Evaporation = Coefficient*Wind Speed Correction Factor*(Saturation Vapour Pressure-Actual Vapour Pressure)
Vapour Pressure of Water at given Temperature for Evaporation in Water Bodies
Go Saturation Vapour Pressure = (Evaporation from Water Body/Proportionality Constant)+Actual Vapour Pressure
Vapour Pressure of Air using Dalton's Law
Go Actual Vapour Pressure = Saturation Vapour Pressure-(Evaporation from Water Body/Proportionality Constant)
Dalton's Law of Evaporation
Go Evaporation from Water Body = Proportionality Constant*(Saturation Vapour Pressure-Actual Vapour Pressure)
