Air at 40.4 oC and 40% relative humidity (RH) is cooled at a constant pressure of 1 atm to 14 oC in an air cooler.

a. Draw and label the process flow diagram of the above process.

b. Determine the fraction of the condensed water.

c. Determine the rate at which heat (kJ/s) must be removed to deliver 1 m3/s of humid air at the final condition.

d. If the humid air is not saturated, estimate the rate of heat (kJ/s) that must be removed to deliver 1 m3/s of the humid air at RH=40%.

    Atmospheric air at 32°C and 70% relative humidity passes through a cooling section in an air-conditioning duct where the air is cooled below its dew point and some of the water is removed. The air then passes over a heating section where heat is added until the final temperature is 22°C and the relative humidity is 45%. Assume the process occurs at constant pressure of 1 atm. Using the psychrometric chart, determine: (a) The amount of water removed in the...
