P.1 Regenerative Rankine Cycle A Rankine cycle with an open feedwater heater is shown below, with property data given in the figure. The net power output is 100 MW. Unless otherwise indicated in the figure, the turbines and pumps are isentropic. Determine: (a) The enthalpy at every state, in kJ/kg. (b) The back work ratio (bwr). (c) The overall thermal efficiency n. (d) The mass flow rate of steam through the steam generator. (e) The maximum theoretical efficiency for a cycle operating between the same maximum and minimum temperatures. (f) Sketch the cycle on a T-s diagram.
