Partial Pressure of Water Vapor

Go Pressure of Water Vapor = Saturation Pressure Corresponding to WBT-((Total Pressure of Moist Air-Saturation Pressure Corresponding to WBT)*(Dry Bulb Temperature in °C-Wet Bulb Temperature))/(1544-1.44*Wet Bulb Temperature)

Wet Bulb Temperature using Carrier's Equation Formula

What is wet bulb temperature?

The Wet Bulb temperature is the adiabatic saturation temperature. Wet Bulb temperature can be measured by using a thermometer with the bulb wrapped in wet muslin. The adiabatic evaporation of water from the thermometer bulb and the cooling effect are indicated by a "wet-bulb temperature" lower than the "dry bulb temperature" in the air.
