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.
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 Meter 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

Actual Vapour Pressure: 0.4 Centimeter Mercury (0 °C) --> 0.4 Centimeter Mercury (0 °C) No Conversion Required
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 --> 2.22222222222222 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V = v+(E_m/(C*(1+(u/16)))) --> 0.4+(0.082/(0.36*(1+(2.22222222222222/16))))

Evaluating ... ...

V = 0.6

STEP 3: Convert Result to Output's Unit

799.932 Pascal -->0.6 Centimeter Mercury (0 °C) (Check conversion here)

FINAL ANSWER

0.6 Centimeter Mercury (0 °C) <-- Maximum Vapour Pressure

What is Vapour Pressure ?

Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.

How to Calculate Maximum Vapour Pressure given Evaporation Loss Per Month?

Maximum Vapour Pressure given Evaporation Loss Per Month calculator uses Maximum Vapour Pressure = Actual Vapour Pressure+(Evaporation Loss per Month/(Meyer's Constant*(1+(Mean Wind Velocity/16)))) to calculate the Maximum Vapour Pressure, The Maximum Vapour Pressure given Evaporation Loss Per Month is defined as the highest pressure exerted by a vapor in equilibrium with its liquid at a given temperature, often measured in cm Hg or kPa. Maximum Vapour Pressure is denoted by V symbol.

How to calculate Maximum Vapour Pressure given Evaporation Loss Per Month using this online calculator?
