CW7-LO3-Thermodynamics of fluid flow Steam enters a turbine at a static pressure of 4.5 MPa, a static temperature of 500 °C and a velocity of 200 m/s. At the turbine exit, the static pressure is 100 kPa, static temperature is 150°C and the velocity is 200 m/s. Neglecting the heat transfer during the expansion process, calculate: (a) the total-to-total efficiency, (b) the total-to-static efficiency, (e) the specific work done by the fluid, (d) the enthalpy loss in the turbine, (e) the change in entropy of the expansion process due to the irreversibilities. Answers: (a) 74.8%; b) 73.2%; c) 663.8 kJ/kg: d) 223.37 kJ/kg, e) 0.583 kJ/kg K.
