Log mean temperature difference, ft applied to heat exchangers. problem 4.9-2, p351. oil flowing at the rate of 5.04 kg/s (cpm = 2.09 kj/kg. k) is cooled in a 1-2 heat exchanger from 366.5 k to 344.3 k by 2.02 kg/s of water entering at 283.2 k. the overall heat transfer coefficient u0, is 340 w/m^2 .k. calculate the area required. (hint: a heat balance must first be made to determine the outlet water temperature.)

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
