4.43 Air expands through a turbine from 10 bar, 900 K to 1 bar. 500 K. The inlet velocity is small compared to the exit veloc- ity of 100 m/s. The turbine operates at steady state and devel- ops a power output of 3200 kW. Heat transfer between the tur- bine and its surroundings and potential energy effects are negligible. Calculate the mass flow rate of air, in kg/s, and the exit area, in m.

I need help with a review porblem I cannot solve! thank you Steam enters an adiabatic turbine at 4 MPa, 800K and exits at 8 kPa, 90% quality. Assuming steady state, steady flow conditions, determine: a) The power output of the turbine (MW) if the mass flow rate is 63kg/s. b)The volumetric flow rate at the inlet (m3/s).
I have been working on this problem for a while but I need to figure out how to get the specific enthalpy when the refridgerant exits the system to find the mass flow rate of when the refridgerant exits the system but I don't know how to do this
Problem 4. Consider an adiabatic steam turbine operating at steady-state with a mass flow rate of 12 kg/s. At the inlet, the steam pressure is 10 MPa, the temperature is 450 °C, and the velocity is 80 m/s. At the exit, the pressure is 10 kPa, a quality of 0.92, and a velocity of 50 m/s. Find the change in kinetic energy Wout = ? Steam turbine (kJ/kg), the work out (power generated in MW), and the turbine inlet area (m²).
