WebWhen a constant pressure gradient G = − d p d x is applied between two ends of a long pipe, the flow will not immediately obtain Poiseuille profile, rather it develops through time and reaches the Poiseuille profile at steady state. The Navier–Stokes equations reduce to with initial and boundary conditions, The velocity distribution is given by WebA venturi meter is a way to measure flow in a pipe. The venturi is a section of pipe where the diameter is gradually reduced to some smaller area then gradually increased to the initial diameter To measure the flow in the pipe you measure the pressure at the inlet and then again at the narrowest section of the venturi. Assuming no friction.
