In Rankine cycle the work output from the turbine is given by__________?
Correct answer: B. change of enthaply between inlet and outlet
- A. change of internal energy between inlet and outlet
- B. change of enthaply between inlet and outlet
- C. change of entropy between inlet and outlet
- D. change of temperature between inlet and outlet
Explanation
For steady, adiabatic turbine flow with negligible changes in kinetic and potential energy, turbine specific work equals the enthalpy drop, \(w_t=h_{in}-h_{out}\). Internal energy or entropy changes alone do not give the turbine work.
