Total pressure of moist air given degree of saturation Solution

STEP 0: Pre-Calculation Summary
Formula Used
total_pressure_mixture = ((Degree of saturation-1)*Partial pressure of water vapour in saturated air)/(((Degree of saturation*Partial pressure of water vapour in saturated air)/Pressure of water vapour)-1)
pt = ((S-1)*ps)/(((S*ps)/pv)-1)
This formula uses 3 Variables
Variables Used
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 - Partial pressure of water vapour in saturated air is obtained from the steam tables corresponding to dry bulb temperature. (Measured in Bar)
Pressure of water vapour - 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. (Measured in Bar)
STEP 1: Convert Input(s) to Base Unit
Degree of saturation: 0.2 --> No Conversion Required
Partial pressure of water vapour in saturated air: 80 Bar --> 8000000 Pascal (Check conversion here)
Pressure of water vapour: 60 Bar --> 6000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pt = ((S-1)*ps)/(((S*ps)/pv)-1) --> ((0.2-1)*8000000)/(((0.2*8000000)/6000000)-1)
Evaluating ... ...
pt = 8727272.72727273
STEP 3: Convert Result to Output's Unit
8727272.72727273 Pascal -->87.2727272727273 Bar (Check conversion here)
FINAL ANSWER
87.2727272727273 Bar <-- Total pressure of moist air
