two Carnot engines A and B are connected in series between two

two Carnot engines A and B are connected in series between two thermal reservoirs maintained at 1000 K and 100 K respectively. Engine A receives 1680 kJ of heat from the high temperature reservoir and rejects heat to the Carnot engine B. Engine B takes in heat rejected by engine A and rejects heat to the low temperature reservoir. if engines A and B have equal thermal efficiencies. determine a) the heat rejected by engine B, b)the temperature at which heat is rejected by engine A, and C) the work done during the process by engines A and B respectively. if engines A and B deliver equal work, determine (d) the amount of heat taken in by engine B, and (e) the efficiencies of engines A and B. :2
