A high-pressure air reservoir is connected to the inlet of a convergent-divergent nozzle with an exit to throat area ratio of 2.0. The reservoir pressure is 1 atm (at standard sea level conditions). The exit pressure is 0.80 atm. Assume isentropic flow (except for the possibility of a normal shock inside the nozzle). If a pitot tube is inserted at a cross section which is 1.10 times the throat area in the diverging section, what is the pressure that the pitot tube reads?

Question

A high-pressure air reservoir is connected to the inlet of a convergent-divergent nozzle with an exit to throat area ratio of 2.0. The
reservoir pressure is 1 atm (at standard sea level conditions). The exit pressure is 0.80 atm. Assume isentropic flow (except for the
possibility of a normal shock inside the nozzle). If a pitot tube is inserted at a cross section which is 1.10 times the throat arca in the
diverging section, what is the pressure that lthe pilul tube reads?

100% High pressure water and compressed air are delivered to some operating rooms. Bored one day, with no patients around, you take the cap off the nozzle to see what would happen. Water flows through the vertical pipe and nozzle and then exhausts into the air as shown in the diagram. The water pressure in the pipe at position 1 is 3 atm. The pressure when the water discharges to the air is 1 atm. Position 2 identifies the nozzle, 0.75 m above position 1, where the water flow has been constricted from an 8-cm diameter pipe to a 3-cm diameter nozzle. Assume that the free jet remains a stream of water with a 3-cm diameter. Assume no friction losses.
