A supersonic nozzle possessing an area ratio of 3.0 is supplied from a large reservoir and is allowed to exhaust to atmospheric pressure (101.3 kPa). Determine the range of reservoir pressures over which a normal shock will appear in the nozzle. For what value of reservoir pressure will the nozzle be perfectly expanded with supersonic flow at the exit plane? Find the minimum reservoir pressure to produce sonic flow at the nozzle throat. Assume isentropic flow except for shocks with ? = 1.4

A convergent–divergent nozzle has an exit area to throat area ratio of 4. It is supplied with air from a large reservoir in which the pressure is kept at 500 kPa and it discharges into another large reservoir in which the pressure is kept at 10 kPa. Expansion waves form at the exit edges of the nozzle causing the discharge flow to be directed outward. Find the angle that the edge of the discharge flow makes to the axis of...

Air is flowing through a nozzle, from a reservoir with pressure of 600 kPa and temperature of 350 K, with supersonic flow downstream of the throat. A shock occurs in the expanding part of the nozzle where the nozzle area is 9 times larger than the throat area. What is the pressure immediately downstream of the shock, in kilopascals?

WORKOUT #6 Consider a nozzle with exit-to-throat area ratio of 4.884 that exhausts in a room at ambient conditions (i.e., pb = 1atm). a) Calculate the plenum pressure necessary to choke the flow at the throat but not allowing for a supersonic solution to be established in the divergent section. (20pts) b) Calculate the plenum pressure necessary to allow for a fully supersonic solution throughout the divergent section assuming that a normal shock is located just at the exit of...

1.      Air enters a converging-diverging nozzle with a total pressure of 1100 kPa and a total temperature of 127°C. The exit area to throat area ratio is 1.8. The throat area is 5 cm2. The velocity at the throat is sonic and the diverging section acts as a nozzle. The diverging section is now acts as a supersonic nozzle. Assume that a normal shock stands in the exit plane of the nozzle. Determine the following: a.       The static pressure and...

The stagnation pressure and temperature of air supplied to a convergent/divergent nozzle are held constant at values of 430K and 600kPa. The nozzle has an outlet area of 0.09m2 and an exit to throat area ratio of 2.51. (i) Calculate the exit pressure required to produce a normal shock at the exit plane of the nozzle. (ii) Calculate the mass flow rate of air through the nozzle when there is a normal shock at the exit plane. (iii) Calculate the...
