E = K_o*(e_s-e_a)
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 = K_o*(e_s-e_a) --> 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
