Efficiency of the engine in the above questions is

Carnot engine is an ideal heat engine, which converts heat energy into mechanical energy. Efficiency of Carnot engine is given by eta =1 - (T_2 // T_1) , where T_1 is temperature of source and T_1 , is temperature of sink. If Q_1 is the amount of heat absorbed/cycle from the source, Q_2 is the amount of heat rejected/cycle to the sink and W is the amount of useful work done/cycle, then W= Q_1 -Q_2 and (Q_2)/(Q_1) = (T_2)/(T_1) Efficiency of the engine in the above question is .if source and sink temperature respectively 227 and 127 .

Work done //cycle by the engine in the above questions is

Efficiency of Carnot engine

Efficiency of heat engine is defined as the

Describe heat engine. Define efficieny of heat engine. Mention two reasons for which the efficiency of a heat engine becomes low.

Efficiency of Carnot engine is 100% if

Assertion: Efficiency of a heat engine can't be greater than efficiency of Carnot engine. Reason: Effieciency of any engine is never 100%

Assertion: Efficiency of a heat engine can't be greater than efficiency of Carnot engine. Reason: Effieciency of any engine is never 100%

Efficiency of a Carnot engine is large when
