Atmospheric air at a flow rate of 3 kg/s (on dry basis) enters cooling and dehumidifying coil with an enthalpy of 85 kJ/kg of dry air and a humidity ratio of 19 grams/kg of dry air. The air leaves the coil with an enthalpy of 43 kJ/kg of dry air and a humidity ratio of 8 grams/kg of dry air. If the condensate water leaves the coil with an enthalpy of 67kJ/kg, the required cooling capacity of the coil in kW is
(a) 75.0 (b) 123.8
(c) 128.2 (d) 159.0
