Question

A Carnot heat engine has a maximum efficiency of 55 %. It takes certain amount of heat from a source, converts a part of it into work and rejects the remaining heat towards the heat sink. If the temperature of the heat source is 600 K then, find the temperature of the heat sink. ​

Answer 1

η=Total amount of heat absorbed per cycleNet work done per cycle

or η=Q1W

∴η=Q1Q1−Q2

or η=1−Q1Q2

as Q1Q2=T1T2

∴η=1
