A steam power plant consists of a boiler, a two-stage turbine, a pump, and a condenser. Superheated steam enters the first turbine stage at temperature and pressure, Tℎℎ and Pℎℎ, expands to a lower pressure, Pm, is reheated to temperature Tm, and enters the second stage at Tm and Pm. The condenser and boiler pressures are Po and Pℎℎ, respectively, and the isentropic efficiencies of both turbine stages is .a) Sketch the plant schematically and label appropriate state points, letting state 1 correspond to the inlet to the first turbine stage. b) Briefly describe how the isentropic outlet state of the first turbine stage is determined. Hint (and as given in lecture notes): Look at the entropies, 1= supℎ (Tℎℎ,Pℎℎ), and (Pm).c) Assume that we did the analysis in b) and found that state 2 is in the two phase region. Show how the quality, x2, , for an isentropic (first) turbine stage is calculated. d) Show how the isentropic outlet enthalpy, ℎ2, , for the first turbine stage is determined. e) Show how the actual outlet enthalpy, ℎ2,, for the first turbine stage is determined. f) Assuming that the inlet and outlet states for the second turbine stage are in the superheated vapor and two phase regions, respectively, show in detail how the inlet enthalpy and the (actual) outlet enthalpy are determined. g) Show in detail how the remaining state enthalpies (across the isentropic pump) are determined. h) Derive (and please don’t simply copy) the thermal efficiency expression, stated in terms of state enthalpies, for this steam power plant.
