A device with an inlet cross-sectional area of 1 ft2 receives oxygen flowing at M=0.2 with pt=100 psia and Tt=1000 ºR. The gas flow process is reversible through this well-insulated device, which involves no work transfer. At the exit plane, the static pressure is measured to be 14.7 psia. Calculate the following fluid and flow parameters using the EES unit system: 1. Static density, velocity, and mass flow rate at the inlet plane; 2. Static temperature & density, Mach number, velocity, and cross-sectional area at the exit plane.
