1. Air (an ideal gas here) at 100. psia and 150.°F flows through a pipe in a factory with a velocity of 10.0 ft/s. The pipe is located 75.0 ft above the floor. Determine the specific flow availability of the air in the pipe when the local environment (ground state) is at 14.7 psia and 70.0°F.
2. Saturated water vapor enters an isentropic turbine of a power plant at 4.00 MPa and exits at 1.00 × 10-3 MPa. Neglecting kinetic and potential energy effects, determine the difference in specific flow availability between the entrance and exit of the turbine. Use saturated liquid water at 20.0°C as the local environment (ground state).
