❓Question:
7) Two reversible heat engines A and B are arranged in series, A rejecting heat directly to B
.Engine A receives 200kJ at a temperature of 421℃ from a hot source, while engine B is in
communication with a cold sink at a temperature of 4.4℃. If the work output of A is twice that of
B, find a) the intermediate temperature between A and B ,b)the efficiency of each engine c) the
heat rejected to the cold sink.
