A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...
