Psychrometric process A room has dimensions of approximately 10m x 10m x 3m. Assume the air inside the room to be at T= 20 oC, P = 100 kPa, Relative Humidity = 50% a. If all of the water vapor in the air of the room could be converted to liquid at the same temperature, what is the volume of the liquid (mL)? b. If the room temperature were slowly cooled without changing the composition of air, at what temperature would you expect to see condensation occurring (oC)?
