In many engineering applications the local flow velocity vector field is not known in every point and the only accessible velocity is the bulk velocity (or average flow velocity) which is the ratio between the volume flow rate and the cross sectional area , given by . WebJan 1, 2024 · The pipe diameter vs flow rate: In a fluid passing through a pipe, a reduction in the diameter of the pipe can compress the flowing fluid. It flows faster, which increases the flow rate. And if the diameter increases, then the flow rate reduces. The pipe size and flow: The water pipe pressure remains the same on both facets of the segment of ...
