Question

Steam enters a turbine at a static pressure of 6 MPa , a static temperature of 600 °C and a velocity of 250 m/s. At the turbine exit, the static

pressure is 100 kPa, static temperature is 150 c and the velocity is 150 m/s. Neglecting the heat transfer during the expansion process, calculate: The total-to-total efficiency. The total-to-static efficiency. The specific work done by the fluid. The enthalpy loss in the turbine. Draw the Moiller diagram for this turbine
