The relationship tells us that flow rate is directly proportional to both the magnitude of the average velocity (hereafter referred to as the speed) and the size of a river, pipe, or other conduit.

v = 1.273 q / d2(2) where v = velocity (m/s) q = volume flow (m3/s) d = pipe inside diameter (m)

Learn the formula, steps, and real-world examples in minutes. Ever wondered how fast a liquid moves in a pipe? That’s where a Flow to Velocity Calculator helps. It takes the flow rate and pipe size, then …

How do I calculate fluid velocity from flow rate? To determine fluid velocity from the volumetric flow rate, you need to divide it by the cross-sectional area of the substance.

For each calculated flow speed a conversion scale will be displayed with a range of values for flow versus speed for the same cross sectional area. The formula used by this calculator to calculate the …

Converting flow rate to velocity involves these steps: Determine the flow rate (Q) in appropriate units. Measure or calculate the cross-sectional area (A) of the flow path. Divide the flow rate by the area to …

V = A · v. If area is measured in square feet and velocity in feet per second, Equation 1 results in >volumetric flow rate measured in cubic feet per second. Other common units for volumetric flow …

Feb 4, 2024 · v is the velocity of the fluid. The Flow rate Q can also be defined to be the volume of fluid passing by some position through an area during a period of time. t is the period of time taken. …

Oct 1, 2025 · Enter the volumetric flow rate and the cross-sectional area into the calculator to determine the velocity.

The relationship tells us that flow rate is directly proportional to both the magnitude of the average velocity (hereafter referred to as the speed) and the size of a river, pipe, or other conduit.
