Partial pressure of vapor given vapor density Solution

STEP 0: Pre-Calculation Summary
Formula Used
Pressure of water vapour = Total pressure of moist air-((Vapor density*287*Dry Bulb Temperature)/Specific Humidity)
pv = pt-((ρv*287*td)/ω)
This formula uses 5 Variables
Variables Used
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.
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.
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.
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
Total pressure of moist air: 100 Bar --> 10000000 Pascal (Check conversion here)
Vapor density: 10 Kilogram per Meter³ --> 10 Kilogram per Meter³ No Conversion Required
Dry Bulb Temperature: 350 Kelvin --> 350 Kelvin No Conversion Required
Specific Humidity: 0.8 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pv = pt-((ρv*287*td)/ω) --> 10000000-((10*287*350)/0.8)
Evaluating ... ...
pv = 8744375
STEP 3: Convert Result to Output's Unit
8744375 Pascal -->87.44375 Bar (Check conversion here)
FINAL ANSWER
87.44375 Bar <-- Pressure of water vapour
(Calculation completed in 00.016 seconds)
