WebFriction factor is plotted vs. Reynolds number and relative roughness on a Moody chart. Relative roughness is defined as the pipe roughness height, ε, divided by the inside … WebAs per the moody diagram we have, that in laminar regime friction factor is only affected by Reynolds number while in turbulent regime, at very high Reynolds number it depends only on...
WebMay 26, 2024 · you can work out a version of the Reynolds number commonly used for non-Newtonian flows. For n < 1: the fluid is pseudoplastic (shear-thinning) For n > 1: the fluid is dilatant (shear-thickening) As Piya mentioned, the effective or apparent viscosity should also be defined as μ app = K ( T) ( d u d r) n − 1
WebAnswer (1 of 2): The Moody diagram represents the complete friction factor map for laminar and all turbulent regions of pipe flows. It is used commonly in estimating the friction factor in pipe flow. In the Moody diagram, the abscissa is the Reynolds number Re, and the ordinate is the resistance ... oh this was such a bad ideaFrom the chart, it is evident that the friction factor is never zero, even for smooth pipes because of some roughness at the microscopic level. The friction factor for laminar flow of Newtonian fluids in round tubes is often taken to be: = where Re is the Reynolds number of the flow. See more The Fanning friction factor, named after John Thomas Fanning, is a dimensionless number used as a local parameter in continuum mechanics calculations. It is defined as the ratio between the local shear stress and … See more This friction factor is one-fourth of the Darcy friction factor, so attention must be paid to note which one of these is meant in the "friction factor" chart or equation consulted.
