Air at 1 atm 30 C and 80% relative humidity passes over the cold evaporator coil of an air conditioner at constant pressure. The air and condensate leave the coil at 18C. The moist air flow rate is 0.02 kg/s. using the psychrometric chart determine the following:
i) The dry air mass flow rate (kg/s)
ii) The condensate mass flow rate (kg/h)
iii) The heat transfer from the moist air (kJ/s)
