Q6) Air flows isentropically through a duct. At section 1 the area

Q6) Air flows isentropically through a duct. At section 1 the area is 0.05 m and V = 180 m/s, p=500 kPa, and T = 470 K. Compute (a) To, (b) M, (c) po, and (d) A*. If at section 2 the area is 0.036 m, compute M and p if the flow is (e) subsonic, or (f) supersonic. Answers: 486 K, 0.414, 563 kPa, 0.0323 m. subbsonic: 0.6758, 415 kPa, supersonic: 1.4001, 177 kPa.
