Question

3. Water steadily enters a steam gas turbine at 60 bar, 500 °C at very low velocity and exits at 1 bar and quality of 0.1, and a velocity of

100 m/s. The mass flow rate of water is 10 kg/s. The heat loss from this turbine to air is 150 kW. You can ignore the change in potential energy (14 points) (a) Draw a schematic Figure of steam turbine and have all known parameters clearly marked. (2Points) (b) Find power output from this turbine, in kW. (8 points) (c) Find cross-section area of the exit port of this steam turbine, in m. (4 Points)
