A carnot engine operates with source at `127^(@)C` and sink at `27^(@)C`. If the source supplies `40kJ` of heat energy. The work done by the engine is

Text Solution

Verified by Experts

The correct Answer is:
10
`Q_1 = 40 kJ :. Eta = 1 - (T_2)/(T_1) = W/(Q_1)`
`implies W = Q_1 [1 - (T_2)/(T_2)] = 40 kJ [1 - 300/400] = 10 kJ`
