Question
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.
