Steam enters a turbine at 1.50 MPa and 700.°C and exits the turbine at 0.200 MPa and 400.°C. The process is steady flow, steady state, and adiabatic. The system boundary temperature is 35.0°C. Determine the following on the basis of a steam flow rate of 6.30 kg/s:
a. The entropy production rate of the turbine.
b. The work transport energy efficiency of the turbine.
c. The turbine's actual output power.
