This calculator calculates the partial pressure of water vapour in saturated air given degree of saturation using total pressure of moist air, degree of saturation, pressure of water vapour values.
Formula:
ps = ((1/pt)+((S/pv)*(1-(pv/pt))))^(-1)
Where,pt = Total pressure of moist air
s = Degree of saturation
pv = Pressure of water vapour
ps = Partial_pressure_saturated_air
