SUPERHEATED( NEED NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE).
One kg of dry and saturated vapor enters to the turbine at 6.0 MPa. Steam leaves thisturbine stage at a pressure of 0.008 Mpa. Calculate the quality of steam at exit of turbine,heat rejected, heat added, cycle efficiency and engine efficiency.(Note: Draw the schematic and T-s diagram)
The steam rate to a turbine for variable output is controlled by a throttle valve in the inlet line.Steam is supplied to the throttle valve at 1,700 kPa and 225°C. During a test run, the pressure atthe turbine inlet is 1000 kPa, the exhaust steam at 10 kPa has a quality of 0.95, the steam flowrate is 0.5 kg/s, and the power output of the turbine is 180kW.
1. What are the heat losses from the turbine?
2. What would be the power output if the steam supplied to the throttle valve were expandedisentropically to the final pressure?
