Air at 20°C flows in a convergent-divergent channel with a 5 cm diameter throat and 10 cm diameter outlet section. The flow takes place from a reservoir to the atmosphere. a) calculate the velocity before the shock wave (m/s) b) calculate the velocity at the throat (m/) c) What should be the reservoir pressure (kpa) for a normal shock wave to occur at the outlet of the channel?

An engineer claims that the flow of SAE 30W oil, at 20 °C,through a 5-cm-diameter smooth pipe at 1 million N/h, islaminar. Do you agree? A million newtons is a lot, so thissounds like an awfully high flow rate.
A converging elbow tirms water to a nozzle in a vertical plane, The elbow cross section diameter is (20 cm) at the inlet, and (10 cm) at the outlet. The water volume flow rate is (200 L/s) and the elbow inlet pressure is unknown but it discharge the water 1o the atmosphere (101.325 kpa). Calculate the horizontal and vertical force required to old the elbow in place. (neglect the weight of elbow and water).
