A turbine receives 8 kg/s of air at 9 MPa, 677 C and 60 m/s (pressure, temperature and velocity). It discharges the air at a temperature of 77 C and a velocity of 15 m/s. In addition, there is heat transfer from the turbine to the surroundings for 150 kW. Find the power produced by the turbine in kW and its isentropic efficiency. You may use specific heats at the average temperature.

According to the Carnot cycle, the thermal efficiency of a working heat machine is 28%, and water vapor is used as the working fluid. Heat transfer to the working fluid occurs at 350°C, and at this time the fluid passes from a saturated liquid state to a saturated vapor state. Since 5 kg of fluid circulates per hour in the cycle, find the power of this heat machine using the entropy of evaporation.
Air is used as the working fluid in a turbine. At the inlet, the air is at 1100 K, 1050 kPa. It is flowing at a rate of 10 kg/s, having a velocity of 30 m/s. At the outlet, the air is 500 K, 98.61 kPa, and flowing at 45 m/s.
