Suppose the air in problem 4 fills a room that has a volume of 3000 ft3. The air is dehumidified at constant dry bulb temperature to a relative humidity of 30%. a) Locate the final state on the same psychrometric chart. Label the initial and final states, and connect them with a process arrow. b) How much water, in lbm, is removed from the air during dehumidification? c) How much energy, in Btu, is removed from the air during dehumidification? d) What is the air's dewpoint temperature, F, at the final state?

Please do step by step solution. I will rate you accordingly.
