Steam enters a two-stage turbine with reheat operating at steady state as shown in Fig. P6.165. The steam enters turbine 1 with a mass flow rate of 120,000 lb/h at 1000 lbf/in.\(^{2}\), 800\(^{\circ}\)F and expands to a pressure of 60 lbf/in.\(^{2}\) From there, the steam enters the reheater where it is heated at constant pressure to 350\(^{\circ}\)C before entering turbine 2 and expanding to a final pressure of 1 lbf/in.\(^{2}\) The turbines operate adiabatically with isentropic efficiencies of 88% and 85%, respectively. Kinetic and potential energy effects can be neglected. Determine the net power developed by the two turbines and the rate of heat transfer in the reheater, each in Btu/h.
