An air conditioner consists of heating and evaporative cooling sections. The air, where the atmospheric pressure is 101.325 kPa, enters the heating section at 20 °C and 30% relative humidity with a flow rate of 35 m3/min, and exits from the evaporative cooling section at 25 °C and 60% relative humidity. a) The temperature and relative humidity of the air leaving the heating section. b) The amount of heat transfer per unit time to the air in the heating section c) Calculate the mass of water added to the air per unit time in the evaporative cooler. d) In order to prevent condensation on the glasses of a person with glasses entering such an environment, what should the temperature of the glasses glass be?
