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.
Maximum Vapour Pressure - (Measured in Centimeter Mercury (0 °C)) - The Maximum Vapour Pressure refers to the highest pressure exerted by a vapour in equilibrium with its liquid at a given temperature, often measured in cm Hg or kPa.
Actual Vapour Pressure - (Measured in Centimeter Mercury (0 °C)) - The Actual vapour pressure refers to the pressure exerted by the water vapour present in the air, reflecting the current humidity and temperature, typically measured in cm Hg or kPa.
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)
Maximum Vapour Pressure: 0.6 Centimeter Mercury (0 °C) --> 0.6 Centimeter Mercury (0 °C) No Conversion Required
Actual Vapour Pressure: 0.4 Centimeter Mercury (0 °C) --> 0.4 Centimeter Mercury (0 °C) No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pa = (1.456-(E/(C'*(0.44+(0.0732*u))*(V-v))))/0.00732 --> (1.456-(0.0829/(0.75*(0.44+(0.0732*2.22222222222222))*(0.6-0.4))))/0.00732
Evaluating ... ...
Pa = 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
