- The mean wall shear stress in a pipe or open channel is expressed in terms of the Darcy Weisbach friction factor as:
- I think I can find out what I want using that and the darcy friction factor formula, but I'm not entirely sure how.
- In which \ rho is the density of air in the shaft or roadway under consideration and f is Fanning friction factor ( dimensionless ).
- Relative roughness is not a parameter in any of the equations because the friction factor of Bingham plastic fluids is not sensitive to pipe roughness.
- Where f is the Darcy friction factor that can either be obtained from the Moody chart or for smooth tubes from correlation developed by Petukhov:
- Moody diagram showing the Darcy-Weisbach friction factor " f " " D " plotted against Reynolds number Re for various relative roughness ? / " D"
- What I call friction factors are some negative characteristics normally associated with geniuses who are under a lot of pressure, or people who are just obnoxious.
- One must keep in mind, however, that the value of the Fanning friction factor can be difficult to determine for supersonic and especially hypersonic flow velocities.
- Where q _ s * is the Einstein nondimensionalization for sediment volumetric discharge per unit width, c _ f is a friction factor, and \ tau * is the Shields stress.

- For the turbulent flow regime, the relationship between the Fanning friction factor and the Reynolds number is more complex and is governed by the Colebrook equation which is implicit in f:
- For example, they played an important role in the calculation of the Perrin friction factors, which contributed to the awarding of the 1926 Nobel Prize in Physics to Jean Baptiste Perrin.
- The rate of decline of the interaction ( called alternatively, the impedance or friction factor, or the utility or propensity function ) has to be empirically measured, and varies by context.
- Both " Swamee-Aggarwal " equation and the " Darby-Melson " equation can be combined to give an explicit equation for determining the friction factor of Bingham plastic fluids in any regime.
- It is important to remember that because humans propel through the water in a turbulent fashion ( compared to fish ), the reduced friction factor is small when compared with other variables.
- Depends on different flow conditions ( laminar, turbulent, shapes of entrance, etc . ), the Nusselt number has different dependence on Reynolds number, Prandtl number and the friction factor of the flow.
