Question

define Carnot engine along with its operation cycle and derive efficiency .(solve this)

Answer 1

Carnot heat engine is a reversible engine and it's work as a refrigerator. It absorbs heat Q1 from the source at a temp. T1 does amount of work W and rejected heat Q2 to the sink at temp. T2 , (T2 less than T1).

Efficiency of Carnot is (eta) n =( Q1 - Q2 ) / Q1
n = 1 - T1 / T2
