Question

Steam at 1.6 MPa and 350°C enters a steam turbine at a flow rate of 16 kg/s. The
steam leaves the turbine as a saturated vapor at 30°C. The turbine delivers 9 MW of
power. The turbine is insulated, but not perfectly. The average temperature of the
insulation on the outer surface of the turbine is 70°C. The figure below shows this
turbine and its operating conditions. Determine the entropy generation rate for the
turbine.
