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...

(10 pts) Six-thousand cubic feet per minutes (C.F.M.) of atmospheric air at 28°C (dry bulb) having a wet bulb temperature of 23°C is to be cooled in an air conditioning system. The air conditioning system lowers the dry bulb temperature of the air to 20° C. Cooling with dehumidification is accomplished using chilled water loop. The chilled water enters the loop at 5°C at a rate of 280 kg/min and experience a 5°C temperature increase. The atmospheric pressure is 1...
