n: a dimensionless number defined as Re =ruD/m Where D = inside diameter of the pipe u = mean flow velocity r = density of the fluid m= dynamic viscosity, all in consistent units.
n: A demensionless number,which be used to judge the flowing condition of the fluid .Its code is Re.
an experimental number used in fluid flow to predict the flow velocity at which the flow regime moves from laminar flow through a transition range and into turbulent flow. It is the dimensionless ratio of inertial forces to viscous forces in flowing fluid
