The boiling point of water at a pressure of 50 atm is 538 K.Compare the theoretical efficiencies of a stem engine operating between the boiling point of water at
1 atm pressure

Explanation

`T_(1)=265+273=538K`
`T_(2)=100+273=373K`
`eta=((T_(1)-T_(2))/(T_(1)))xx100`
`=((538-373)/(538))xx100`
`=(165)/(538)xx100`
`eta=30.66%`
