Vapour Pressure of Water at given Temperature for Evaporation in Water Bodies Solution

STEP 0: Pre-Calculation Summary

Formula Used

Saturation Vapour Pressure = (Evaporation from Water Body/Proportionality Constant)+Actual Vapour Pressure
e_s = (E/K_o)+e_a
This formula uses 4 Variables

Variables Used

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.
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.
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

Evaporation from Water Body: 2907 --> No Conversion Required
Proportionality Constant: 1.5 --> No Conversion Required
Actual Vapour Pressure: 3 Millimeter Mercury (0 °C) --> 399.966 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

e_s = (E/K_o)+e_a --> (2907/1.5)+399.966

Evaluating ... ...

e_s = 2337.966

STEP 3: Convert Result to Output's Unit

2337.966 Pascal -->17.5362355800243 Millimeter Mercury (0 °C) (Check conversion here)

FINAL ANSWER

17.5362355800243 ≈ 17.53624 Millimeter Mercury (0 °C) <-- Saturation Vapour Pressure
