Superheated steam at 8.30 kg/s, 1.00 MPa, and 400.°C enters a horizontal, stationary, insulated nozzle with a negligible velocity and expands to 10.0 × 10-3 MPa. The friction and other irreversibilities within the nozzle cause the exit velocity to be only 85.0% of that produced by an isentropic expansion. Taking the local environment (ground state) to be that of saturated liquid water at 20.0°C, determine
a. The inlet specific flow availability.
b. The exit specific flow availability.
c. The irreversibility rate inside the nozzle.
