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. WebUsing the following formula we can easily calculate the Velocity of a flow from Volume Flow Rate of a fluid: Flow Rate, Where Q= Volume Flow Rate in m3/s. A =Cross sectional area of the passage through which fluid is flowing in m2. Now, bar v=Q/A=Volume Flow Rate/Cross sectional area of the pipe.
WebFeb 20, 2024 · Flow is proportional to pressure difference and inversely proportional to resistance: Q = P2 − P1 R. For laminar flow in a tube, Poiseuille’s law for resistance states that R = 8ηl πr4. Poiseuille’s law for flow in a tube is Q = (P2 − P1)πr4 8ηl. The pressure drop caused by flow and resistance is given by P2 − P1 = RQ.
