In an air conditioning system air at a flow rate of 2 kg/s enters the cooling coil at 25°c and 50% rh (relative humidity) and leaves the cooling coil at 11°c and 90% rh. the apparatus dew point of the cooling coil is 7°c. find: i. the required cooling capacity of the coil ii. sensible heat factor for the process, and iii. by-pass factor of the cooling coil. assume the barometric pressure to be 1 atm.
