Completely solve and box the final answers. Write legibly In a steam turbine plant, a single bleed is taken from the turbine for regenerative feed water heating (closed). The inlet of the turbine is supplied with steam at 3.4 MPa and 320 C and exhausts at 0.15 MPa for bled steam. The remaining will expand which in turn exhausts at 0.01 MPa. The working fluid is throttled via throttle valve after the closed feed water heater going to the condenser. By drawing the system and showing the process on T-s diagram determine (a) the mass fraction of the bled steam, then (b) the work net and the thermal efficiency of the system.
