Below is the thing which I have attempted:
eta of Heat engine 2(between the reservoirs A&C)=(Ta-Tc)/Ta
therefore,eta of heat engine 1(between reservoirs A,B&C)=\alpha[(Ta-Tc)/Ta]
where eta is the efficiency of the heat engine.
Now heat absorbed by heat engine 1=2Q1
Heat rejected by heat...
A reversible engine works between three thermal reservoirs-A,B and C.The engine absorbs an equal amount of heat from the thermal reservoirs A & B kept at temperatures Ta and Tb respectively,and rejects heat to the thermal reservoir C kept at temperature Tc.The efficiency of the engine is\alpha...
