7. Air [R=1715 ft·lb/(slug R), cp = 6003 ft-lb/(slug-R)] flows steadily, as shown in the figure,...
Steam flows steadily through a turbine at a rate of 45,000 lbm/hr, entering at 1,000 lbf/in2 and 900oF and leaving at a pressure of 5 lbf/in2. If the power generated by the turbine is 1.37x107 Btu/hr and the turbine is cooled at a rate of 7x106 Btu/hr, determine the temperature of the steam at the exit [oF]. Show the inlet and exit states on a P-v diagram.
Problem 4.029 Air expands through a turbine operating at steady state. At the inlet, P1 = 150 lbf/in.2, T1 = 1400ºR, and at the exit, P2 = 14.8 lbf/in., T2 = 700°R. The mass flow rate of air entering the turbine is 5 lb/s, and 65,000 Btu/h of energy is rejected by heat transfer. Neglecting kinetic and potential energy effects, determine the power developed, in hp. hp We = the tolerance is +/-2%
/6 pts) A quasi-1-D steady adiabatic flow of NEON GAS (R 412 Jkg-K, Cp 1030 J/kg-K & k 53) flows through a gradually contoured channel as shown. Friction is insignificant except for the shock. The mass flowrate is 70.2 kg/s State properties are only partially known. The flow velocity just after the normal shock is A12mis at section "Y. A) Find the stagnation temperature. T。= K and the critical temperature. T., K B) Find the flow Mach number just before...
