WebWhat is pipe velocity? This represents the speed of a fluid in the pipe and what needs to be taken in consideration is that this speed is not uniform across the section area so … WebGiven the characteristic velocity scale, U, and length scale, L, for a system, the Reynolds number is Re = UL/ν, where ν is the kinematic viscosity of the fluid. For most surface water systems the characteristic length scale is the basin-scale. Because this scale is typically large (1 m to 100's km), most surface water systems are turbulent. palliser hiring
