Saturation Pressure Corresponding to Wet Bulb Temperature Solution

STEP 0: Pre-Calculation Summary

Formula Used

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)))
p_w = (p_v+p_t*((t_db-T_w)/(1544-1.44*T_w)))/(1+((t_db-T_w)/(1544-1.44*T_w)))
This formula uses 5 Variables

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.
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.
Wet Bulb Temperature - Wet Bulb Temperature is the temperature of the wet bulb and denoted by the symbol Tw.

STEP 1: Convert Input(s) to Base Unit

Pressure of Water Vapor: 60 Bar --> 6000000 Pascal (Check conversion here)
Total Pressure of Moist Air: 100 Bar --> 10000000 Pascal (Check conversion here)
Dry Bulb Temperature in °C: 110 --> No Conversion Required
Wet Bulb Temperature: 14 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p_w = (p_v+p_t*((t_db-T_w)/(1544-1.44*T_w)))/(1+((t_db-T_w)/(1544-1.44*T_w))) --> (6000000+10000000*((110-14)/(1544-1.44*14)))/(1+((110-14)/(1544-1.44*14)))

Evaluating ... ...

Saturation Pressure Corresponding to Wet Bulb Temperature Formula

What is wet bulb tempearture?

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.
