A Rankine cycle with reheat produces 1 MW of net power. Theboiler operates at 15 MPa and has an outlet temperature of 800 K.The condenser operates at atmospheric pressure (1 atm). Theoperating point of this cycle is such that the water exiting thelow pressure turbine has no liquid present to prevent damageto theturbine (hint: what does this say about quality at this point?).Assume the pump and second turbine stage are both isentropic, butthe first turbine stage has an isentropic efficiency of 90%. Assumethe steam is reheated at a pressure of 1 MPa.
Find:
(A)The mass flow rate of steam through the turbines
(B)The required heat input
(C)The required flow rate of fuel given a heating value of 50MJ/kg
(D)Plot the state points on a T-s diagram with lines of constantpressure at the boiler,reheat, and condenser pressures.
