Flow rate to velocity equation
WebChoked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect.When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent-divergent nozzle or a valve in a pipe) into … WebMar 27, 2016 · 2. I was wondering how I can calculate the velocity of gas through a pipe. The gas, assuming ideal behavior, in a pipe (cylinder) of volume of 222.4 L has a pressure of 1.95 atmospheres and a density of 2.25 kg/m 3. Knowing that there will be turbulent flow, the equation, V = 2 Δ P ρ ( 4 f Δ x D − 1) can be used.
