Steam enters the isentropic turbine of power plant at 200. psia and 500.°F.
How much does the change in specific flow availability between the inlet and exit of the turbine increase if the exit pressure is lowered from 14.7 psia to 1.00 psia?
Neglect all kinetic and potential energy effects. Use saturated liquid water at 80.0°F as the local environment (ground state).
