3. In an air conditioning system air at a flow rate of 2 kg's enters the cooling coil at 25C and 50% Relative Humidity (RH) and leaves the cooling coil at 11C and 90% RH The apparatus dew point (ADP) of the cooling coil is 7 C. Find a) The required cooling capacity of the coil, b) Sensible Heat Factor for the process, and c) By-pass factor of the cooling coil. Assume the barometric pressure to be 1 atm. Assume the condensate water to leave the coil at ADP, (how-29.26 kJ/kg) (c) Sketch the process in the psychrometric chart denoting sensible and latent heat.
