Steam flows steadily through a turbine. The steam enters the turbine at a pressure of 4.5 MPa and a temperature of 700 °C. The steam exits the turbine at a pressure of 0.5 MPa with a velocity of 170 m/s. The mass flow rate of the steam is 25 kg/s and the inlet velocity is negligible. The rate of heat loss is 440 kW and the power generated by the turbine is 22 MW. Calculate the temperature at the exit of the turbine (°C).

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
