Steam (18kg/kmol) at 1600psi and 1000°F enters a turbine operating at steady state as shown. P. = 1600 psi Turbine 22% of the entering mass flow is extracted by duct T = 1000° F 2 at 160psi and 450°F. The rest of the steam exits 2 3 Pz = 1 psi at duct 3 at 1psi and 102°F. The turbine develops a power output of 9x108 Btu/hr. Heat transfer to T, = 102°F P2 = 160 psi the surroundings accounts for 7% of the power T, = 450°F output. Neglecting kinetic and potential energy effects and assuming that steam behaves as ideal gas at constant y=1.35, a) Determine the fluid's specific gas constant in Btu/lb/°R. b) Determine the mass flow rate of the steam entering the turbine in lb/hr (Answer: 2.738x10 lb/hr) c) How would your result in part b) change if the inlet pressure is 1700psi and WHY?
