Total Pressure of Moist Air given Vapour Density Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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 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.
Specific Humidity - Specific Humidity is the ratio of the mass of water vapor to the total mass of the air parcel.
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
Specific Humidity: 0.25 --> No Conversion Required
