WebVenturi flow meters, like all other types of differential pressure flow meters, function on the principles of the Bernoulli equation, which states that as the speed of the flow of a fluid increases, pressure loss occurs. Venturi tubes are available in sizes up to 72” and can pass 25 to 50% more flow than an orifice with the same pressure drop. Web12 de oct. de 2024 · For constant mass flow, see this link on choked flow by NASA. Just to quickly summarize that: mass flow is maximum at Mach equal to 1, which happens at the throat of a conventional rocket nozzle. The equation that then gives this mass flow is: m ˙ = A t p c R ⋅ T c γ ( γ + 1 2) − γ + 1 2 ( γ − 1)

Webchange by passing through a shock wave becoming subsonic again. Whichever of the last two sub-options occurs the ﬂow through the converging/diverging nozzle is said to be choked for the following reason. If the ﬂow becomes sonic (M = 1) in the throat then, at this location, u∗ = c =(γRT∗)12 (Bof2) http://imartinez.etsiae.upm.es/~isidoro/bk3/c17/Nozzles.pdf
