In an intermediate superheated steam cycle, water vapor is 4 MPapressure, 440 oC high, isentropic and 0.80 high
After entering the pressure turbine, it expands to 0.4 MPa and theintermediate superheater is again up to 440 oC.
it is heated and enters the low pressure turbine, whose isentropicefficiency is also 0.80. 40 oC from condenser
The fluid that works as a saturated liquid at temperature ispressed into the boiler with a pump with an isentropic efficiencyof 0.90.
By accepting the entry of steam into the high pressure turbine as 1point,
A) Show the cycle in the T-S diagram.
B) The degree of dryness of the steam at the outlet of the lowpressure turbine
C) Thermal efficiency of the cycle
D) Calculate the second law efficiency of the cycle.
