Air at 38°c and 97% relative humidity is to be cooled to 14°c and fed into a plant area at a rate of 510m3/min. (a) calculate the rate (kg/min) at which water condenses. (b) calculate the cooling requirement in tons 1 ton of cooling 12; 000 btu/h, assuming that the enthalpy of water vapor is that of saturated steam at the same temperature and the enthalpy of dry air is given by the expression
