Q13. Steam expands in a turbine steadily at a mass flowrate of m - 44 Mg/h, entering at 8 MPa, 500°C and 78 m/s, and leaving at 40 kPa, 79% quality and 51 m/s. If the power generated by the turbine is 7.1 MW and the surrounding has a constant temperature of 23 °C For this problem you must use property tables (from the textbook). Determine the magnitude of the heat loss rate (in MW) to the surroundings.
Q14. Steam expands in a turbine steadily at a mass flowrate of th - 45 Mg/h, entering at 8 MPa, 500°C and 78 m/s, and leaving at 40 kPa, 82% quality and 48 m/s. If the power generated by the turbine is 7.1 MW and the surrounding has a constant temperature of 22 °C For this problem you must use property tables (from the textbook). Determine the rate of entropy generation during this process, $ in kW/K. (Hint, you need to consider the entropy change via heat transfer to the surrounding too.) gen
