Change in Vapour Pressure given Evaporation Loss Per Month Solution

STEP 0: Pre-Calculation Summary

Formula Used

Change in Vapour Pressure = Evaporation Loss per Month/(Meyer's Constant*(1+(Mean Wind Velocity/16)))
δV = E_m/(C*(1+(u/16)))
This formula uses 4 Variables

Variables Used

Change in Vapour Pressure - (Measured in Centimeter Mercury (0 °C)) - Change in Vapour Pressure refers to the difference between maximum vapour pressure and actual vapour pressure.
Evaporation Loss per Month - (Measured in Meter) - Evaporation Loss per Month refer to the amount of water that transitions from liquid to vapor and escapes into the atmosphere over a specific time period, typically measured on a monthly basis.
Meyer's Constant - The Meyer's Constant refers to an empirical coefficient in the Meyer evaporation formula, 1.1 for deep water and 1.5 for shallow water.
Mean Wind Velocity - (Measured in Centimeter per Second) - Mean Wind Velocity refers to the wind in kilometers per hour at a height of about 9 meters above the ground.

STEP 1: Convert Input(s) to Base Unit

Evaporation Loss per Month: 8.2 Centimeter --> 0.082 Meter (Check conversion here)
Meyer's Constant: 0.36 --> No Conversion Required
Mean Wind Velocity: 8 Kilometer per Hour --> 222.222222222222 Centimeter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

δV = E_m/(C*(1+(u/16))) --> 0.082/(0.36*(1+(222.222222222222/16)))

Evaluating ... ...

δV = 0.0152985074626866

STEP 3: Convert Result to Output's Unit

20.396276119403 Pascal -->0.0152985074626866 Centimeter Mercury (0 °C) (Check conversion here)

FINAL ANSWER

0.0152985074626866 ≈ 0.015299 Centimeter Mercury (0 °C) <-- Change in Vapour Pressure
