Please i need the answer of part c because i did not understand it Enginecring Themedynamics 1 Page |6 Problem 4: Entropy (25 points) Sleam at 6 MPa and 500°C enters a two-stage adiabatic turbine at a rate of 900 liters min. Ten percent of the sacam is extracted at the nd of the first stage at a prossure of 1.2 MPa for other use. Th remainder of the stcam is further expanded in the second stage and leaves the turbine at 20 kPa Assume steady-state process and one-dimensional flow Determine the power output of the turbine, assuming a) the process is reversible (15 pes) b) the turbine has an isentropie efficiency of 88 percenm. (5 pts ) Discuss the sources of irmeversibility in the two-stage turbine. (5pts)
Explanation / Answer
SOURCES OF IRREVERSIBILITY MEANS LOSSES HAPPENING IN THE TURBINE
