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) - Partial Pressure of Dry Air is the pressure exerted by dry air in a mixture of gases, typically measured in humid environments.
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.
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

Pressure of Water Vapor: 28.66972 Bar --> 2866972 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*2866972)/0.25

Evaluating ... ...

p_a = 7133026.336

STEP 3: Convert Result to Output's Unit

7133026.336 Pascal -->71.33026336 Bar (Check conversion here)

What is Dry Air?

Specific humidity is a measure of the amount of water vapor present in the air, expressed as the mass of water vapor per unit mass of air (including the water vapor). It is usually measured in grams of water vapor per kilogram of air. Unlike relative humidity, specific humidity does not change with temperature or pressure, making it a stable indicator of the moisture content in the air. Specific humidity is important in meteorology, climate studies, and understanding moisture-related processes in the atmosphere.
