Question:
Air at 38°C and 97% relative humidity is to be cooled to 18°C and fed into a plant area at a race of 510m3/min.
(a) Calculate the rate (kg/mm) 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 H (kJ/mol) = 0.0291(T(°C) — 25]
