Atmospheric air at 95 kpa, 30 degrees celcius, and 75% humidity is to be conditioned at constant pressure so that it enters a room at 20 degrees celcius and 40% relative humidity. During the conditioning process, the air entering the conditioning system is first cooled below its dew point by a cooling coil. At the end of the cooling process, the water condenses from the airstream until specific humidity of air reaches its desired value. Once the desired humidity ratio is reached, heat is added to the airstream via heating coils until the desired outlet conditions are achieved. If the volumetric flow rate of the air stream is 80 m^3/,min, calculated the
a) amount of liquid water removed and the total heat and the total heat transfer through the water removal
b) total heat removal rate in the dehumidification section
c) total heat addition rate in the heating section
d) total net heat transfer rate during the entire conditioning process
