500 kJ/min heat is supplied to a heat
engine at 727o C. It rejects heat at 900 kJ/min at 223o C.
This type of engine is ________.
Ideal
irreversible
Impossible
practical
Impossible
Since, the
efficiency of heat engine is coming out as more than the efficiency of Carnot
engine, therefore this type of engine is impossible.
Hence, the correct option is (C).
