Two carnot engine A and B operate respectively between `500 K` and `400 K` , and `400 K` and `300 K`. What is the percentage difference in their efficiencies ?

Text Solution

Verified by Experts

`eta_(A)= 1-((T_(2))/(T_(1)))_(A)= 1-(400)/(500)`
`1/5= 1/5xx100%= 20%`
`eta_(B)= 1-((T_(2))/(T_(1)))_(B)- 1-(300)/(400)`
`= 1/4= 1/4xx100= 25%`
`eta_(B)-eta_(A)= 25-20 = 5%`
