Review of conditions for pipe flow analysis: laminar versus turbulent flow; fully-developed versus developing flow; viscous flow in straight sections versus loss in fittings. Derive and solve the ODE for the velocity profile in fully-developed laminar flow in a round pipe. Obtain the formula for average velocity and the formula relating flow rate to pressure drop. Generalize the results to turbulent flow with dimensional analysis and an overview of the physics of the turbulent velocity profile. Introduce the Darcy friction factor and the Moody chart.
