Partial Pressure of Water Vapor given Specific Humidity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Pressure of Water Vapor = Total Pressure of Moist Air/(1+0.622/Specific Humidity)
pv = pt/(1+0.622/ω)
This formula uses 3 Variables
Variables Used
Pressure of Water Vapor - (Measured in Pascal) - Pressure of Water Vapor is the amount of water vapor present in the air, which affects the humidity and atmospheric conditions around us.
Total Pressure of Moist Air - (Measured in Pascal) - Total Pressure of Moist Air is the pressure exerted by a mixture of air and water vapor in a given volume of air at a specific temperature.
Specific Humidity - Specific Humidity is the ratio of the mass of water vapor to the total mass of air in a given volume of air at a specific temperature.
STEP 1: Convert Input(s) to Base Unit
Total Pressure of Moist Air: 100 Bar --> 10000000 Pascal (Check conversion ​here)
Specific Humidity: 0.25 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pv = pt/(1+0.622/ω) --> 10000000/(1+0.622/0.25)
Evaluating ... ...
pv = 2866972.47706422
STEP 3: Convert Result to Output's Unit
2866972.47706422 Pascal -->28.6697247706422 Bar (Check conversion ​here)
FINAL ANSWER
28.6697247706422 28.66972 Bar <-- Pressure of Water Vapor
(Calculation completed in 00.008 seconds)
