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 4 Variables
Variables Used
Total pressure of moist air - 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. (Measured in Bar)
Vapor density - Vapor density is defined as the mass of water vapor present in 1 m3 of dry air. It is also called absolute humidity. (Measured in Kilogram per Meter³)
Dry Bulb Temperature - Dry bulb temperature is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture. (Measured in Kelvin)
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: 100 Kelvin --> 100 Kelvin No Conversion Required
Specific Humidity: 1 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pv = pt-((ρv*287*td)/ω) --> 10000000-((10*287*100)/1)
Evaluating ... ...
pv = 9713000
STEP 3: Convert Result to Output's Unit
9713000 Pascal -->97.13 Bar (Check conversion here)
FINAL ANSWER
97.13 Bar <-- Pressure of water vapour
