Question

Steam enters a turbine at 450 lbf/in.², 900 F, expands in a reversible adiabatic process and exhausts at 130 F. Changes in kinetic and potential energies between the inlet and the exit of the turbine are small. The power output of the turbine is 800 Btu/s. What is the mass flow rate of steam through the turbine?

Answer 1

C.V. Turbine, Steady single inlet and exit flows.

Adiabatic:
