Equation for Parameter Including Wind Velocity and Saturation Deficit Solution

STEP 0: Pre-Calculation Summary

Formula Used

Actual Mean Vapor Pressure = 0.35*(1+(Mean Wind Velocity/160))*(Saturation Vapour Pressure-Actual Vapour Pressure)
E_a = 0.35*(1+(W_v/160))*(e_s-e_a)
This formula uses 4 Variables

Variables Used

Actual Mean Vapor Pressure - Actual Mean Vapor Pressure is the vapor pressure exerted by the water in the air.
Mean Wind Velocity - (Measured in Meter per Second) - Mean Wind Velocity is the average velocity of the wind at certain height.
Saturation Vapour Pressure - (Measured in Millimeter Mercury (0 °C)) - 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 Millimeter Mercury (0 °C)) - 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

Mean Wind Velocity: 2 Centimeter per Second --> 0.02 Meter per Second (Check conversion here)
Saturation Vapour Pressure: 17.54 Millimeter Mercury (0 °C) --> 17.54 Millimeter Mercury (0 °C) No Conversion Required
Actual Vapour Pressure: 3 Millimeter Mercury (0 °C) --> 3 Millimeter Mercury (0 °C) No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E_a = 0.35*(1+(W_v/160))*(e_s-e_a) --> 0.35*(1+(0.02/160))*(17.54-3)

Evaluating ... ...

E_a = 5.089636125

STEP 3: Convert Result to Output's Unit

5.089636125 --> No Conversion Required

FINAL ANSWER

5.089636125 ≈ 5.089636 <-- Actual Mean Vapor Pressure
