 Moreover, the flow rate depends upon the channel from which the liquid is passing or the area of the pipe, and the velocity of the liquid. Besides, the formula isFluid flow rate = area of the pipe or channel velocity of the liquid

• ### What is the formula used to calculate flow velocity?

• The formula used by this calculator to calculate the flow velocity is: v = Q / A Symbols v = Flow velocity Q = Volumetric flow rate A = Cross-sectional area n.b.

• ### How to calculate volumetric flow rate?

• The formula used by this calculator to calculate the flow velocity is: v = Q / A. Symbols. v = Flow velocity; Q = Volumetric flow rate; A = Cross-sectional area; n.b. This formula assumes uniform flow conditions within the entire cross-sectional area, without any friction losses near to surfaces. Volumetric Flow Rate Measured

• ### How do you find the flow rate of a pipe?

• The following formula is used by this calculator to populate the value for the flow rate, pipe diameter or water velocity, whichever is unknown: V = 0.408 Q/D2. V = Water Velocity; Q = Flow Rate; D = Pipe Diameter.

• ### What is the relationship between average velocity and flow rate?

• where is the cross-sectional area and is the average velocity. This equation seems logical enough. 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.
