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 vapour)
ω = (ρv*td*287)/(pt-pv)
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 Meter³) - 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 vapour - (Measured in Pascal) - Pressure of water vapour 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: 10 Kilogram per Meter³ --> 10 Kilogram per Meter³ No Conversion Required
Dry Bulb Temperature: 350 Kelvin --> 350 Kelvin No Conversion Required
Total pressure of moist air: 100 Bar --> 10000000 Pascal (Check conversion here)
Pressure of water vapour: 60 Bar --> 6000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ω = (ρv*td*287)/(pt-pv) --> (10*350*287)/(10000000-6000000)
Evaluating ... ...
ω = 0.251125
STEP 3: Convert Result to Output's Unit
0.251125 --> No Conversion Required
FINAL ANSWER
0.251125 <-- Specific Humidity
