Theoretical flow rate equation
Webb5 nov. 2024 · The SI unit of flow rate is m 3 /s, but other rates can be used, such as L/min. Flow rate and velocity are related by Q = Av where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into a pipe must equal the mass flowing out of the pipe. WebbEquation 3 . Equation 4 . Therefore the flow velocity at the throat of the venturi and the volumetric flow rate are directly proportional to the square root of the differential pressure. The pressures at the upstream section …
