10 The Reynolds number is a dimensionless fluid flow in pipes. The Reynolds number is defincd as DVp Re where D, is the inside diameter of the pipe, V is the average velocity of the fluid in the pipe, p is the fluid density and u is the absolute viscosity of the fluid. For flow in pipes, a Reynolds number of less than 2000 indicates that the flow is laminar, while a value of greater than 10,000 indicates that the flow is turbulent. For a pipe diameter of 5 em, and fluid of density 1 g/cm and viscosity of 1 centipoise, find the minimum velocity that results in turbulent flow.
