Steam flows steadily through a turbine at 20,000 kg/h, entering at 40 bar and 440 oC, and leaving at 0.2 bar with 90% quality. A heat loss of 20 kJ/kg occurs. The inlet pipe has a 12 cm diameter, and the exhaust section is rectangular with dimensions of 0.6 m by 0.7 m. Calculate; a. The kinetic energy change b. The output power in kW.
