About this paper

MEF 360: A tutorial on viscous (real) incompressible pipe flow, covering Reynolds number, flow-regime classification, the Darcy friction factor, and head losses; no institution or course code is printed on the source. The original document contains 7 exercises; three fully self-contained numerical problems (Exercises 1, 2, and 4) were transcribed and solved in full, covering: classifying the flow regime (laminar, transitional, or turbulent) of water and heavy fuel oil at different temperatures in a fixed-diameter pipe; a complete pipe-flow analysis of heavy fuel oil (kinematic viscosity, velocity, Reynolds number, laminar friction coefficient, and head loss); and an inverse problem deducing the linear head-loss coefficient, Reynolds number, and kinematic viscosity of an unknown fluid from a measured pressure drop. The remaining exercises (turbulent-regime friction correlations, serpentine-coil minor-loss networks, and a pump shaft-power problem) were omitted for scope.
