Using Entropy Data and ConceptsSteam enters a turbine
Chapter 6, Problem 17P(choose chapter or problem)
Steam enters a turbine operating at steady state at 1 MPa, \(200^{\circ} \mathrm{C}\) and exits at \(40^{\circ} \mathrm{C}\) with a quality of 83%. Stray heat transfer and kinetic and potential energy effects are negligible. Determine (a) the power developed by the turbine, in kJ per kg of steam flowing, (b) the change in specific entropy from inlet to exit, in kJ/K per kg of steam flowing.

QUESTION:
Steam enters a turbine operating at steady state at 1 MPa, \(200^{\circ} \mathrm{C}\) and exits at \(40^{\circ} \mathrm{C}\) with a quality of 83%. Stray heat transfer and kinetic and potential energy effects are negligible. Determine (a) the power developed by the turbine, in kJ per kg of steam flowing, (b) the change in specific entropy from inlet to exit, in kJ/K per kg of steam flowing.
ANSWER:Solution
Step 1 of 4
In this problem, we have to find the power developed by the turbine and the change in specific entropy. The free body diagram of this problem is given below.
