Can anyone help me with the below? Air is drawn into a compressor at normal temperature and pressure (N.T.P) and compressed to a pressure of 6 bar gauge. After compression the air is delivered at 1.2 m3 min-1 and cooled to a temperature of 30°C, at which point condensate is collected at the rate of 2 litres per hour. Estimate the FAD (N.T.P) of the compressor, and the relative humidity of the air entering the compressor. I have calculated the FAD to be 2.6324 m3 min-1 but I am unsure on the relative humidity?
