Specific Humidity given Partial Pressure of Water Vapor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Humidity = (0.622*Pressure of Water Vapor)/(Total Pressure of Moist Air-Pressure of Water Vapor)
ω = (0.622*p_v)/(p_t-p_v)
This formula uses 3 Variables

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Pressure of Water Vapor: 28.66972 Bar --> 2866972 Pascal (Check conversion here)
Total Pressure of Moist Air: 100 Bar --> 10000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ω = (0.622*p_v)/(p_t-p_v) --> (0.622*2866972)/(10000000-2866972)

Evaluating ... ...

ω = 0.249999941679747

STEP 3: Convert Result to Output's Unit

0.249999941679747 --> No Conversion Required

FINAL ANSWER

0.249999941679747 ≈ 0.25 <-- Specific Humidity

What is Cold Air?

Cold air refers to air that has a lower temperature compared to the surrounding environment or a reference point. It typically feels cool or chilly to the touch and is denser than warm air. Cold air is often associated with high-pressure systems, where cooler temperatures lead to greater air density and more stable atmospheric conditions. In weather systems, cold air can lead to the formation of frost, snow, or other cold-weather phenomena, especially when it interacts with warmer, moist air. Cold air plays a significant role in climate, weather patterns, and the comfort of living environments.
