Partial Pressure of Dry Air given Specific Humidity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Partial Pressure of Dry Air = (0.622*Pressure of Water Vapor)/Specific Humidity
p_a = (0.622*p_v)/ω
This formula uses 3 Variables

Variables Used

Partial Pressure of Dry Air - (Measured in Pascal) - The Partial Pressure of Dry Air is the pressure that is exerted by the dry air in the mixture of dry air and water vapor called moist air.
Pressure of Water Vapor - (Measured in Pascal) - Pressure of Water Vapor is the pressure exerted by the water vapour in the moist air or the mixture of dry air and water vapour.
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

Pressure of Water Vapor: 60 Bar --> 6000000 Pascal (Check conversion here)
Specific Humidity: 0.25 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p_a = (0.622*p_v)/ω --> (0.622*6000000)/0.25

Evaluating ... ...

p_a = 14928000

STEP 3: Convert Result to Output's Unit

14928000 Pascal -->149.28 Bar (Check conversion here)

FINAL ANSWER

149.28 Bar <-- Partial Pressure of Dry Air

(Calculation completed in 00.004 seconds)
