In a divergent duct
Did you know?
Websimple device is a convergent - divergent duct (The front section's cross-sectional area A decreases in the flow direction, and the back section's cross-sectional area increases in the flow direction. Somewhere in between the inlet and exit of the duct, there is a minimum area, called the throat.) Let A1 and A2 denote the 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.

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. … 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 equation, we obtain: 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.
