A laboratory space to be maintained at 24oC DB and 50% RH experiences a sensible-cooling load of 42 kW and a latent load of 18 kW. Because the latent load is heavy, the air-conditioning system is equipped for reheating the air leaving the cooling coil. The cooling coil has been selected to provide outlet air at 9 oC and 95% RH. What is (a) the air rate and (b) the temperature of supply air? Air pressure is 101.325 kPa
