Fanning flow
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 the local flow kinetic energy density: $${\displaystyle f={\frac {\tau }{\rho {\frac {u^{2}}{2}}}}}$$ 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. Of the two, the Fanning friction factor is the more … See more • Fanning, J.T. (1896). A practical treatise on hydraulic and water-supply engineering. D. Van Nostrand. ISBN 978-5-87581-042-8.

WebQuestion. For fluid flow in pipes, friction is described by a dimensionless number, the Fanning friction factor f. The Fanning friction factor is dependent on a number of parameters related to the size of the pipe and the fluid, which can all be represented by another dimensionless quantity, the Reynolds number Re.

In actual practice, empirical flow formulas … The Fanno flow model begins with a differential equation that relates the change in Mach number with respect to the length of the duct, dM/dx. Other terms in the differential equation are the heat capacity ratio, γ, the Fanning friction factor, f, and the hydraulic diameter, Dh: Assuming the Fanning friction factor is a constant along the duct wall, the diffe…
