Flow in pipe reynolds number
WebThe type of flow is determined by a non-dimensional number called the Reynolds number for a pipe flow. Re = (VD/v) Where, D = Diameter of pipe V = Mean velocity of the flow in pipe ... If the Reynolds number is more than 4000, then the flow is called turbulent flow. If the Reynolds number is between 2000 and 4000, the flow may be laminar or ... WebPopular answers (1) The Reynold's number (Re) is defined by the fluid flow velocity (v), density (rho) and the pipe diameter (D) and divided by the dynamics viscosity (mu). Since you have a ...
