QUESTION
Problem is shown below. Really not sure where to start, what equations to use?
Oxygen flows into an insulated device with initial conditions as follows: p1 = 30 psia,T1 = 750°R, and V1 = 639 ft/sec. The area changes from A1 = 6 ft2 to A2 = 5 ft2.(a) Compute M1, pt1, and Tt1.(b) Is this device a nozzle or diffuser?(c) Determine M2, p2, and T2 if there are no losses
