Air at 800C and 100 kPa with a molal humidity of 0.012 kmol H2O/kmol dry air is used as drying medium. It goes out of the drier at 40 oC and 750 mmHg with a humidity of 0.065 kmol H2O/kg dry air. If the water evaporated in the drier is 30 kg/min, calculate: a) kg of product per minute b) the volume of the outgoing air in m3/min
