9.16 Steam at a pressure of 2 × 106 N/m² and a temperature of 250 °C flows steadily nto a turbine with negligible velocity. The steam leaves the turbine at a pressure of 15 × 10³ N/m² with a velocity of 200 m/s. The heat-transfer rate from the turbine casing to the atmosphere is 160 × 10³ W. The power developed by the turbine is 3430 × 10³ W. The mass flow rate is 6-1 kg/s. Determine the dryness of the steam leaving the turbine and the cross-sectional area of the exit section. 9.16 Steam at a pressure of 2 × 106 N/m² and a temperature of 250 °C flows steadily nto a turbine with negligible velocity.
