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 2 Variables
Variables Used
Total pressure of moist air - 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. (Measured in Bar)
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: 1 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pv = pt*((1+(0.622/ω))^(-1)) --> 10000000*((1+(0.622/1))^(-1))
Evaluating ... ...
pv = 6165228.1134402
STEP 3: Convert Result to Output's Unit
6165228.1134402 Pascal -->61.652281134402 Bar (Check conversion here)
FINAL ANSWER
61.652281134402 Bar <-- Pressure of water vapour
