QUESTION:
Steam enters an adiabatic turbine at 10 MPa and 5008C and leaves at 10 kPa with a quality of 90 percent. Neglecting the changes in kinetic and potential energies, determine the mass flow rate required for a power output of 5 MW.
ANSWER:Step 1 of 4
Steam expands in a turbine. The mass flow rate of steam for a power output of 
Assumptions are
1. This is a steady-flow process since there is no change with time.
2. Kinetic and potential energy changes are negligible.
3. The device is adiabatic and thus heat transfer is negligible.
