This formula uses 5 Variables

Variables Used

Atmospheric Pressure - (Measured in Centimeter Mercury (0 °C)) - Atmospheric pressure refers to the force exerted by the weight of the atmosphere on a surface, typically measured in pascals (Pa), millibars (mb), or inches of mercury (inHg).
Evaporation Loss per Day - (Measured in Meter) - Evaporation Loss per Day refers to the amount of water lost from a surface due to evaporation within a single day, typically measured in millimeters (mm).
Rohwer's Formula Constant - Rohwer's Formula Constant refers to an empirical coefficient used in Rohwer's equation to estimate evaporation rates, adjusting for local climatic conditions.
Mean Wind Velocity - (Measured in Meter per Second) - Mean Wind Velocity refers to the wind in kilometers per hour at a height of about 9 meters above the ground.
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.

STEP 1: Convert Input(s) to Base Unit

Evaporation Loss per Day: 8.29 Centimeter --> 0.0829 Meter (Check conversion here)
Rohwer's Formula Constant: 0.75 --> No Conversion Required
Mean Wind Velocity: 8 Kilometer per Hour --> 2.22222222222222 Meter per Second (Check conversion here)
Change in Vapour Pressure: 0.2 Centimeter Mercury (0 °C) --> 0.2 Centimeter Mercury (0 °C) No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_a = (1.456-(E/(C'*(0.44+(0.0732*u))*δV)))/0.00732 --> (1.456-(0.0829/(0.75*(0.44+(0.0732*2.22222222222222))*0.2)))/0.00732

Evaluating ... ...

P_a = 73.6290439576381

STEP 3: Convert Result to Output's Unit

98163.7139852023 Pascal -->73.6290439576381 Centimeter Mercury (0 °C) (Check conversion here)

FINAL ANSWER

73.6290439576381 ≈ 73.62904 Centimeter Mercury (0 °C) <-- Atmospheric Pressure
