Question

Calculate efficiency of carnols engine working between 300k and 600k

Answer 1

Given source temperature T₁ = 600 K and

sink temperature T₂ = 300 K

As mentioned in the question it is a Carnot engine, hence follows reversible process.

Thus Efficiency of Carnot engine

η = (T₁ - T₂)/T₂

η = 1 -(300/600) = 0.5

η = 50 %
