Degree of Saturation given partial pressure of water vapour Solution

STEP 0: Pre-Calculation Summary
Formula Used
Degree of saturation = (Pressure of water vapour/Partial pressure of water vapour in saturated air)*((1-(Partial pressure of water vapour in saturated air/Total pressure of moist air))/(1-(Pressure of water vapour/Total pressure of moist air)))
S = (pv/ps)*((1-(ps/pt))/(1-(pv/pt)))
This formula uses 4 Variables
Variables Used
Degree of saturation - Degree of saturation is the ratio of the volume of water to the volume of voids.
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.
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.
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
Pressure of water vapour: 60 Bar --> 6000000 Pascal (Check conversion here)
Partial pressure of water vapour in saturated air: 80 Bar --> 8000000 Pascal (Check conversion here)
Total pressure of moist air: 100 Bar --> 10000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
S = (pv/ps)*((1-(ps/pt))/(1-(pv/pt))) --> (6000000/8000000)*((1-(8000000/10000000))/(1-(6000000/10000000)))
Evaluating ... ...
S = 0.375
STEP 3: Convert Result to Output's Unit
0.375 --> No Conversion Required
FINAL ANSWER
0.375 <-- Degree of saturation
