What is Mean Velocity of Flow ?
The mean velocity of flow refers to the average speed at which a fluid moves through a cross-section of a pipe or channel. Since the velocity of fluid is not uniform across the entire cross-section (due to friction at the boundaries, which slows the flow near the walls), the mean velocity provides a useful measure to represent the overall flow speed.
In a real-world flow scenario, the fluid near the pipe walls experiences friction, causing slower movement, while fluid in the center moves faster. The mean velocity is a single value that represents the overall velocity of the flow, averaging these differences.
How to Calculate Mean Velocity of Fluid Flow?
Mean Velocity of Fluid Flow calculator uses Mean Velocity = (1/(8*Dynamic Viscosity))*Pressure Gradient*Radius of pipe^2 to calculate the Mean Velocity, The Mean Velocity of Fluid Flow is defined as average velocity of stream flowing the pipe measured over the entire length. Mean Velocity is denoted by Vmean symbol.
How to calculate Mean Velocity of Fluid Flow using this online calculator? To use this online calculator for Mean Velocity of Fluid Flow, enter Dynamic Viscosity (μ), Pressure Gradient (dp|dr) & Radius of pipe (R) and hit the calculate button. Here is how the Mean Velocity of Fluid Flow calculation can be explained with given input values -> 0.039675 = (1/(8*1.02))*17*2^2.
