Web4.5 Consider the flow of air through a convergent-divergent duct, such as the venturi tube described in Prob. 4.4. The inlet, throat, and exit areas are 3, 1.5, and 2 m respectively. The inlet and exit pressures are 1.02x 105 and 1.00 × 105 N/m2 respectively. Calculate the flow velocity at the throat.
WebEngineering Mechanical Engineering supersonic nozzle is also a convergent–divergent duct, which is fed by a large reservoir at the inlet to the nozzle. In the reservoir of the nozzle, the pressure and temperature are 10 atm and 300 K, respectively. At … Webheld constant by a pressure regulator, and back pressure Pb (downstream the nozzle) is adjustable by a valve. If the downstream valve is closed, the entire nozzle is at a pressure …
WebOct 30, 2013 · In order to expand an internal steady flow through a duct from subsonic to supersonic speed the duct has to be convergent – divergent in shape. If the nozzle contour is not proper, shock waves may occur inside the duct. WebConsider the incompressible flow of water through a divergent duct. The inlet velocity and area are 5 ft/s and 10 ft^2 , respectively. If the exit area is 4 times the inlet area, calculate the water flow velocity at the exit. In Prob. 1 , calculate the pressure difference between the exit and the inlet. The density of water is 62.4 lbm /ft 3.
This nozzle configuration is called a convergent-divergent, or CD, nozzle. In a CD nozzle, the hot exhaust leaves the combustion chamber and converges down to the minimum area, or throat, of the nozzle. The throat size is chosen to choke the flow and set the mass flow rate through the system. See more Ramjets, scramjets, and rockets all use nozzles to accelerate hot exhaust to produce thrust as described by Newton's third law of motion. The amount of thrust produced by the … See more where mdot is the mass flow rate, r is the gas density, V is the gas velocity, and A is the cross-sectional flow area. If we differentiate this … See more Combining this equation for the change in pressure with the momentum equation we obtain: using the definition of the Mach number M = V / a. Now we substitute this value of (dr /r) into the … See more
WebProblem 4.4 • An instrument used to measure the airspeed on many early low-speed airplanes, principally during 1919 to 1930, was the venturi tube.
