QUESTION 5 (20 MARKS) Steam injection is frequently used in air conditioning system for humidification. Moist air at dry bulb temperature of 20 C and wet bulb temperature of 8 C is being humidified by injecting saturated steam at 110 C. The exiting stream after injection has a dew point of 13 C. The rate of dry air is 2 kg/s and the enthalpy of saturated steam at 110 C is 2690.95 kJ/kg. Calculate the (a) steam injection rate in kg/s, and (10 marks) (b) final dry bulb temperature of the exiting moist air. (10 marks)
