Heat supplied to a Carnot engine is 453....

Heat supplied to a Carnot engine is `453.6 kcal`. How much useful work can be done by the engine that works between `10^(@)C` and `100^(@)C`?

Text Solution

Verified by Experts

`T_(2)=100+273=373K,T_(1)=10+273=283K`,
`q_(2)=453.6xx4.184=1897.86kJ`
We know that,
`w=q_(2)*(T_(2)-T_(1))/(T_(2))`
`=1897.86xx((373-283))/(373)`
`=(1897.86xx90)/(373)=457.92kJ`
