Total Pressure of Moist Air given Degree of Saturation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Pressure of Moist Air = ((Degree of Saturation-1)*Partial Pressure of Water Vapour in Saturated Air*Pressure of Water Vapor)/(Degree of Saturation*Partial Pressure of Water Vapour in Saturated Air-Pressure of Water Vapor)
p_t = ((S-1)*p_s*p_v)/(S*p_s-p_v)
This formula uses 4 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.
Degree of Saturation - Degree of saturation is the ratio of the volume of water to the volume of voids.
Partial Pressure of Water Vapour in Saturated Air - (Measured in Pascal) - Partial pressure of water vapour in saturated air is obtained from the steam tables corresponding to dry 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.

STEP 1: Convert Input(s) to Base Unit

Degree of Saturation: 0.2 --> No Conversion Required
Partial Pressure of Water Vapour in Saturated Air: 91 Bar --> 9100000 Pascal (Check conversion here)
Pressure of Water Vapor: 60 Bar --> 6000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p_t = ((S-1)*p_s*p_v)/(S*p_s-p_v) --> ((0.2-1)*9100000*6000000)/(0.2*9100000-6000000)

Evaluating ... ...

p_t = 10449760.7655502

STEP 3: Convert Result to Output's Unit

10449760.7655502 Pascal -->104.497607655502 Bar (Check conversion here)

FINAL ANSWER

104.497607655502 ≈ 104.4976 Bar <-- Total Pressure of Moist Air
