1. Determining fluid flow through pipes and tubes has great relevance in many areas of engineerin gase g and science. In engineering, typical applications include the flow of liquids and s through pipelines and cooling systems. Scientists are interested in topics ranging from flow in blood vessels to nutrient transmission through a plant's vascular system. The resistance to flow in such conduits is parameterized by a dimensionless number called the friction factor. For turbulent flow, the Colebrook Equation provides a...

anbox (31184010sents * Microsoft Word - 1-friction facto X Downloads/midcomp.pdf In fluid flow problems, the flow velocity in a long horizontal pipe depends on the pipe material, pipe geometry and fluid properties in addition to the pump power. For a horizontal pipe with a pump, the friction factor can be obtained from many correlations such as Colebrook-White Equation: 5.0452 Re IOR 2.8257 PDV 1 = -2 108 3.7065 +5.8506 (Re)-0.0001 (1) In which, fis the friction factor and pris the...
