Fanning’s friction factor

The other friction factors in common use are the Newton number and Fanning s friction factor. The relationship between the three is ... [Pg.244]

This / is known as Fanning s friction factor. Using this /, the frictional energy loss Ff for flow in a pipe of length L is given by... [Pg.171]

Pressure drop is important to quantify the process energy requirements and can even be the limiting factor in the design and performance of a monolith reactor. It is related to Darcy s friction factor (four times higher than the Fanning factor) by [41]... [Pg.179]

For turbulent flow, White (1932) gave an equation for the Reynolds number range 15000 to 100000. In terms of the Fanning friction factor, White s equation can be written as... [Pg.84]

Taylor (T4, T6), in two other articles, used the dispersed plug-flow model for turbulent flow, and Aris s treatment also included this case. Taylor and Aris both conclude that an effective axial-dispersion coefficient Dzf can again be used and that this coefficient is now a function of the well known Fanning friction factor. Tichacek et al. (T8) also considered turbulent flow, and found that Dl was quite sensitive to variations in the velocity profile. Aris further used the method for dispersion in a two-phase system with transfer between phases (All), for dispersion in flow through a tube with stagnant pockets (AlO), and for flow with a pulsating velocity (A12). Hawthorn (H7) considered the temperature effect of viscosity on dispersion coefficients he found that they can be altered by a factor of two in laminar flow, but that there is little effect for fully developed turbulent flow. Elder (E4) has considered open-channel flow and diffusion of discrete particles. Bischoff and Levenspiel (B14) extended Aris s theory to include a linear rate process, and used the results to construct comprehensive correlations of dispersion coefficients. [Pg.135]

The Fanning friction factor may be approximated as 0.003 since > 20,000. See Chapter 6 for additional details. Using Bernoulli s equation, the pressure drop in the duct is... [Pg.820]

The subscript s is used in Ap, and to call attention to the fact that in Eqs. (5.7) and (5.7a) these quantities, when they are associated with the Fanning friction factor, relate only to skin friction. If other terms in the Bernoulli equation are present or if form friction is also active, p — p differs from Ap,. If boundary-layer separation occurs, hf is greater than hf. The last term in Eq. (5.7), which includes the friction factor, is written in a manner to show the relation of to the velocity head V j2g. ... [Pg.86]
