Partial pressure of water vapor given specific humidity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Pressure of water vapour = Total pressure of moist air*((1+(0.622/Specific Humidity))^(-1))
pv = pt*((1+(0.622/ω))^(-1))
This formula uses 3 Variables
Variables Used
Pressure of water vapour - (Measured in Pascal) - Pressure of water vapour is the pressure exerted by the water vapour in the moist air or the mixture of dry air and water vapour.
Total pressure of moist air - (Measured in Pascal) - Total pressure of moist air is the pressure exerted by the mixture of air and water vapour which is equal to the sum of the respected pressures. It is also called barometric pressure.
Specific Humidity - Specific Humidity is the ratio of the mass of water vapor to the total mass of the air parcel.
STEP 1: Convert Input(s) to Base Unit
Total pressure of moist air: 100 Bar --> 10000000 Pascal (Check conversion here)
Specific Humidity: 0.8 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pv = pt*((1+(0.622/ω))^(-1)) --> 10000000*((1+(0.622/0.8))^(-1))
Evaluating ... ...
pv = 5625879.04360056
STEP 3: Convert Result to Output's Unit
5625879.04360056 Pascal -->56.2587904360056 Bar (Check conversion here)
FINAL ANSWER
56.2587904360056 Bar <-- Pressure of water vapour
(Calculation completed in 00.000 seconds)
