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.
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 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.
Wet bulb temperature - Wet bulb temperature is the temperature of the wet bulb and denoted by the symbol Tw.
Dry Bulb Temperature in °C - Dry bulb temperature in °C is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture.
STEP 1: Convert Input(s) to Base Unit
Saturation pressure corresponding to WBT: 65 Bar --> 6500000 Pascal (Check conversion here)
Pressure of water vapour: 60 Bar --> 6000000 Pascal (Check conversion here)
Wet bulb temperature: 20 --> No Conversion Required
Dry Bulb Temperature in °C: 90 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pt = (((pw-pv)*(1544-1.44*Tw))/(tdb-Tw))+pw --> (((6500000-6000000)*(1544-1.44*20))/(90-20))+6500000
Evaluating ... ...
pt = 17322857.1428571
STEP 3: Convert Result to Output's Unit
17322857.1428571 Pascal -->173.228571428571 Bar (Check conversion here)
FINAL ANSWER
173.228571428571 Bar <-- Total pressure of moist air

5 Pressure of water vapour Calculators

Wet Bulb Temperature using Carrier's equation
Wet bulb temperature = ((1544*(Saturation pressure corresponding to WBT-Pressure of water vapour))-(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 vapour))-(Total pressure of moist air-Saturation pressure corresponding to WBT)) Go
Saturation pressure corresponding to wet bulb temperature
Saturation pressure corresponding to WBT = (Pressure of water vapour+(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))) Go
Total pressure of moist air using Carrier's equation
Total pressure of moist air = (((Saturation pressure corresponding to WBT-Pressure of water vapour)*(1544-1.44*Wet bulb temperature))/(Dry Bulb Temperature in °C-Wet bulb temperature))+Saturation pressure corresponding to WBT Go
Partial pressure of water vapor
Pressure of water vapour = 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)) Go
Dry Bulb Temperature using Carrier's equation
Dry Bulb Temperature in °C = ((Saturation pressure corresponding to WBT-Pressure of water vapour)*(1544-1.44*Wet bulb temperature)/(Total pressure of moist air-Saturation pressure corresponding to WBT))+Wet bulb temperature Go

Total pressure of moist air using Carrier's equation Formula

Total pressure of moist air = (((Saturation pressure corresponding to WBT-Pressure of water vapour)*(1544-1.44*Wet bulb temperature))/(Dry Bulb Temperature in °C-Wet bulb temperature))+Saturation pressure corresponding to WBT
pt = (((pw-pv)*(1544-1.44*Tw))/(tdb-Tw))+pw

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.
