Transcribed Image Text:Q3→
Steam enters a steam turbine at a pressure of 4 MPa
and a flow rate of 25 kg / s at 450 ° C. At a pressure
of 1 MPa and a temperature of350 ° C, intermediate
steam is drawn from the turbine at a flow rate of 5 kg
/h. The remainder of the steam leaves the turbine at
10 kPa pressure and 0.90 dryness. 200 kW of heat
loss occurs from the turbine to the environment.
Ambient temperature is 25 ° C and pressure is 100
КРа.

a) Calculate the exergy (available work potentials)
of the state points.
b) Find the reversible amount of work and the
actual amount of work during this process.
c) Calculate the amount of irreversibility (exergy
destruction) in this process.
d) Calculate the second-law yield for this process.
