Air enters a heating and humidification system at 5◦C, 50% relative humidity. The air first passes over a heater, and is then humidified with steam. The steam is supplied at 200 kPa pressure and 300◦C. The air leaves the system at 30◦C, 60% relative humidity. (a) Determine the heat transfer to the air, per unit mass dry air. (b) Determine the temperature and relative humidity of the air leaving the heating section (i.e., prior to the humidification section). (c) Determine...

2. An air conditioning system is to take in air at latm 33C, 70% relative humidity and flow rate of 50m3/min and deliver it 23C and 60% relative humidity. The air first flows over the cooling coils, where it is cooled and dehumidified, and then over the resistance heating wires, where it is heated to the desired temperature. Assuming that the condensate is removed from the cooling section at 10C, determine: a) The temperature of the air before it enters...
