Extracted text: 58. 5.3. Oxygen flows into an insulated device with initial conditions as follows: pi= 30 psia, Ti= 750R, and Vi 639 ft/sec. The area changes from A1 6 ft to A2 = 5 ft. (a) Compute Mi, pa, and Tn. (b) Is this device a nozzle or diffuser? (c) Determine M2, p2, and T2 if there are no losses.
