A converging nozzle is connected to a large tank that contains compressed air at 15°C. The nozzle exit area is 0.001 m2. The exhaust is discharged to the atmosphere. To obtain a satisfactory shadow photograph of the flow pattern leaving the nozzle exit, the pressure in the exit plane must be greater than 325 kPa gage. What pressure is required in the tank? What mass flow rate of air must be supplied if the system is to run continuously? Show static and stagnation state points on a Ts diagram.

- The converging-diverging flow domain is shown in Figure 1. The inlet diameter is 0.2 m, the throat diameter is 0.15 m, and the outlet diameter is 0.24 m. The axial distance from the inlet to the throat is 0.30 m—the same as the axial distance from the throat to the outlet. At the inlet section, the stagnation pressure P0 is set to 220 kPa (absolute), while the stagnation temperature T0, at the inlet is set to 300 K.arrow_forwardThe jet engine on a test stand, shown in the figure, admitsair at 20oC and 1 atm at section 1, where the area is 0.5 m2and the velocity is 250 m/s. The fuel-to-air ratio is 1:30.The air leaves at section 2 at atmospheric pressure and ahigher temperature. The exit velocity is 900 m/s and thearea is 0.4 m2. Compute the horizontal test stand reactionRx needed to hold the engine fixed.arrow_forwardHello, Please listen to me carefully. I need "If this tank/converging-diverging nozzle combination was to be used as arocket’s propulsion unit, would it produce more or less thrust as it flewhigher and higher in altitude?" to be answered based on the main question ******Dont solve for the main question as I dont want it. ******arrow_forward
- 1. Calculate the density of air entering the nozzle, if the air leaves a nozzle at a P=1.5atm and T=600K at a velocity of 400m/s. The air enters at 150 m/s and the inlet to exit diameter ratio is 3:1.5.arrow_forwardPlease show your complete solution. Thank you! Air flows in a steady flow manner through a converging tube. At the inlet the pressure is 690kPaabs and the density is 0.838 kg/cu.m. If air enters with a volume flow of 125 cu.m per min at the rate of 94 m/min and the exit section has a diameter of 350mm, determine a.) the mass flow rate, kg/min b.) the diameter of the entrance section and c.) the exit velocity. Assume that the density is constant.arrow_forwardQ5: A converging-diverging nozzle, which is shown in the figure, is supplied with air from a large tank where the pressure is Po and exhausts to the atmosphere with a pressure of Po. The area A at distance x from the throat is given by (A = At (1 + 0.75x/L)), where At is the throat cross- sectional area and Lis the total length of the diverging part of the nozzle. At a certain pressure ratio PoPb, a normal shock wave stands in the nozzle at a point where the Mach number before the shock is 1.7. Find the position of the normal shock wave from the throat, and the pressure ratio P/Po. Ans.: 0.45 L = 0.753 Р. Psarrow_forward
- A piezometer and a Pitot tube are tapped into a horizontal water pipe, as shown in the Figure I belowto measure static and stagnation (static + dynamic) pressures. For the indicated water column heights,determine the velocity at the center of the pipe.

If the measured static pressure was 200 kPa, the measured stagnation pressure was 223 kPa and the air can be treated as an ideal gas what is the air velocity?arrow_forwardVacumm You are designing a vacuum system with a desired equilibrium pressure of 10-7 torr. The turbomolecular pump you are using has a pumping speed of 400 L/s. What is the maximium surface area of the chamber that you can allow, assuming that the outgassing rate per square cm 10-9 torr L/s?

The nozzle throat has a cross-sectional area of 5.5 x 10-3 m2. The hot air enters the nozzle at 300 bar(atm) and 77 °C and exits nozzle at 1 bar(atm). If we have choked flow at the throat, what is the pressure at the throat?
