Determining mass flow rate and exit velocity of compressible flow

WebJul 1, 2024 · Or in other words, a venturimeter is a tube with a constricted throat that increases velocity and decreases pressure. They are used for measuring the flow rate of compressible and incompressible flow in pipelines. The venturimeter basically works on the principle of Bernoulli’s equation. WebAs the flow continues past the throat, the gradual increase in the flow area results in reduction of flow velocity back to the level at section 1, correspondingly the liquid pressure will increase to some value higher than at the throat section. We can calculate the flow rate using the Bernoulli's equation, along with the continuity equation ... howling coyote emoji

WebSo, for a supersonic flow to develop from a reservoir where the velocity is zero, the subsonic flow must first accelerate through a converging area to a throat, followed by continued acceleration through an enlarging area. The nozzles on a rocket designed to place satellites in orbit are constructed using such converging-diverging geometry. WebSep 4, 2024 · A trick here is to realize the pressure is in MPa. Using the English units, the rate is near the same (850 psi): 0.005 ⋅ ( 850 0.688) = 0.5181 in s = 13.16 mm s. The mass burning rate goes out the nozzle, so calculate ρ r A in SI units: ρ = 1.785 g cm 3 = 1785 kg m 3, r = 0.012 m s, A = 55411 mm 2 = 0.055411 m 2, mass flow = 1.187 kg s.

WebTechnical Background. The usual configuration for a converging diverging (CD) nozzle is shown in the figure. Gas flows through the nozzle from a region of high pressure (usually referred to as the chamber) to one of low pressure (referred to as the ambient or tank). The chamber is usually big enough so that any flow velocities here are negligible.
