Air, modeled as an ideal gas, is compressed at steady state from 1 bar, 300 K, to 5 bar, 500 K, with 50 kW of power input.

Need Help going through the process on how to solve this problem. May accidentally be asking this a second time, because the first time I asked it, it didn't show as a pending problem. Steam expands adiabatically through a turbine at steady state. The entering stream is at 750 lbf/in^2, 750°F, and the exiting stream is a saturated vapor at 10 lbf/in^2. Kinetic and potential energy effects are negligible. a. How much work per lb of flow does the turbine produce, in Btu/lbm? b. If the turbine produces 3000 kW of output power, determine the mass flow rate of steam in kg/s. c. If this process were isentropic, the existing stream would no longer be a saturated vapor. Determine the final quality of steam in that case. d. Determine the isentropic turbine efficiency.
8. Steam enters a turbine operating at steady state with a mass flow rate of 3000 kg/h. The turbine develops a power output of 700 kW. At the inlet, the pressure is 40 bar, the temperature is 500°C, and the velocity is 9 m/s. At the exit, the pressure is 0.1 bar, the quality is 0.9 (90%), and the velocity is 30 m/s. Calculate the rate of heat transfer between the turbine and surroundings, in kW.
