Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20Ā°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kgĀ°c) enter at 160Ā°c at a rate of 0.95 kg/s and leave at 95Ā°c. determine the rate of heat transfer to the air and its outlet temperature.
