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
(c) The work done during the process by engines, A and B respectively. If engines
A and B deliver equal work, determine

As their efficiency is same so
ηA = ηB

A heat engine employing a
Carnot cycle with an efficiency
of η = 10% is used as a
refrigerating machine, the
thermal reservoirs being the
same.
