An air conditioner cools 226m3/min of humid air at 36°c and 98% relative humidity to 10°c.
(a) do a degree-of-freedom analysis to prove that enough information is available to determine the required cooling duty (rate of heat transfer).
(b) calculate the rate of condensation of water in the unit and the cooling duty in tons (1 ton = 12,000 btu/h)
