Steam expands in an turbine operating in steady-state conditions with a mass flow rate of 40,000 kg/hr. The steam enters the turbine at 8 MPa and 500 C, and exits as a saturated vapor at 40 kPa. If the power generated by the turbine is 8.2 MW, what is the rate of entropy generation, assuming the surrounds are at 25 C?
