Question 109
XE-ENAT2 marksNeeds review
Steam enters a steam turbine at 10 MPa and 600 °C with a mass flow rate of 16 kg/s. The steam exits the turbine as saturated vapor at 10 kPa. Under steady state condition, the turbine generates 16.2 MW power. If the ambient temperature is 25 °C, the rate of entropy generation in the turbine is ______ kW/K (round off to 2 decimal places).
Neglect the change in kinetic and potential energies of the steam, and use the following property values:
