Specific Humidity given Vapor Density Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Humidity = (Vapor Density*Dry Bulb Temperature*287)/(Total Pressure of Moist Air-Pressure of Water Vapor)
ω = (ρ_v*t_d*287)/(p_t-p_v)
This formula uses 5 Variables

Variables Used

Specific Humidity - Specific Humidity is the ratio of the mass of water vapor to the total mass of the air parcel.
Vapor Density - (Measured in Kilogram per Cubic Meter) - Vapor Density is defined as the mass of water vapor present in 1 m³ of dry air. It is also called absolute humidity.
Dry Bulb Temperature - (Measured in Kelvin) - Dry bulb temperature is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture.
Total Pressure of Moist Air - (Measured in Pascal) - 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.
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.

STEP 1: Convert Input(s) to Base Unit

Vapor Density: 32 Kilogram per Cubic Meter --> 32 Kilogram per Cubic Meter No Conversion Required
Dry Bulb Temperature: 350 Kelvin --> 350 Kelvin No Conversion Required
Total Pressure of Moist Air: 189 Bar --> 18900000 Pascal (Check conversion here)
Pressure of Water Vapor: 60 Bar --> 6000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ω = (ρ_v*t_d*287)/(p_t-p_v) --> (32*350*287)/(18900000-6000000)

Evaluating ... ...

ω = 0.249178294573643

STEP 3: Convert Result to Output's Unit

0.249178294573643 --> No Conversion Required

FINAL ANSWER

0.249178294573643 ≈ 0.249178 <-- Specific Humidity
