General Approach for Pipe Flow • Develop the solution for average fluid velocity using the laminar flow assumption • Examine the Reynolds Number • If turbulent flow is expected, Re>2100 for pipes, then calculate the average velocity using the friction factor. • Recheck the Re to make sure 105>Re>2100
