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 m3min-1and 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.
