Air flows from a reservoir through a convergent-divergent nozzle and then a Fanno flow in the constant-area duct (see figure). The area ratio Ai/Ath of the nozzle is 2.9. The constant-area duct is 50-cm long with a diameter of 1 cm. The friction coefficient in the duct is 0.02. The back pressure is 50 kPa. What is the range of the reservoir pressures that will cause a normal shock to occur in the duct? Pr (2) Pb = 50 kPa

Question
Air flows from a reservoir through a convergent-divergent nozzle and then a Fanno flow in the constant-area duct (see figure). The area ratio A₁/Ath of the nozzle is 2.9. The constant-area duct is 50-cm long with a diameter of 1 cm. The friction coefficient in the duct is 0.02. The back pressure is 50 kPa. What is the range of the reservoir pressures that will cause a normal shock to occur in the duct? Pr 2 Pb = 50 kPa
