Saturation Pressure Corresponding to WBT - (Measured in Pascal) - Saturation Pressure Corresponding to WBT (Wet Bulb Temperature) is the pressure that can be found from the steam table corresponding to wet bulb temperature.
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.
Wet Bulb Temperature - Wet Bulb Temperature is the temperature of the wet bulb and denoted by the symbol Tw.
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.

STEP 1: Convert Input(s) to Base Unit

Saturation Pressure Corresponding to WBT: 65 Bar --> 6500000 Pascal (Check conversion here)
Pressure of Water Vapor: 60 Bar --> 6000000 Pascal (Check conversion here)
Wet Bulb Temperature: 14 --> No Conversion Required
Total Pressure of Moist Air: 100 Bar --> 10000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_db = ((p_w-p_v)*(1544-1.44*T_w)/(p_t-p_w))+T_w --> ((6500000-6000000)*(1544-1.44*14)/(10000000-6500000))+14

Evaluating ... ...

Wet Bulb Temperature using Carrier's Equation

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

Saturation Pressure Corresponding to Wet Bulb Temperature

Go Saturation Pressure Corresponding to WBT = (Pressure of Water Vapor+Total Pressure of Moist Air*((Dry Bulb Temperature in °C-Wet Bulb Temperature)/(1544-1.44*Wet Bulb Temperature)))/(1+((Dry Bulb Temperature in °C-Wet Bulb Temperature)/(1544-1.44*Wet Bulb Temperature)))

Total Pressure of Moist Air using Carrier's Equation

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

Dry Bulb Temperature using Carrier's Equation

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

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)

Dry Bulb Temperature using Carrier's Equation Formula

What is dry bulb tempearture?

The Dry Bulb Temperature refers basically to the ambient air temperature. It is called "Dry Bulb" because the air temperature is indicated by a thermometer not affected by the moisture of the air. When people refer to the temperature of the air they are normally referring to the dry bulb temperature.

How to Calculate Dry Bulb Temperature using Carrier's Equation?
