The Fanning friction factor (named after American engineer John T. 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: [ 1 ] [ 2 ]
Assuming the Fanning friction factor is a constant along the duct wall, the differential equation can be solved easily. [ 2 ] [ 3 ] 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.
Friction factor may refer to: Atkinson friction factor, a measure of the resistance to airflow of a duct; Darcy friction factor, in fluid dynamics; Fanning friction factor, a dimensionless number used as a local parameter in continuum mechanics
If the value of the friction factor is 0.016, then the Fanning friction factor is plotted in the Moody diagram. Note that the nonzero digits in 0.016 are the numerator in the formula for the laminar Fanning friction factor: f = 16 / Re . The procedure above is similar for any available Reynolds number that is an integer power of ten.
Niacin is available as a prescription product, either immediate release (500 mg tablets; prescribed up to 3,000 mg/day) or extended release (500 and 1,000 mg tablets; prescribed up to 2,000 mg/day). In the US, niacin is also available as a dietary supplement at 500 to 1,000 mg/tablet. Niacin has sometimes been used in combination with other ...
Example of a label showing the amount of niacin (Vitamin B3), and specifying to be niacinamide in the ingredient section.. As flour fortification started adding niacin in the US, the United States Government adopted the terms niacin (a shortened form of "nicotinic acid vitamin") and niacinamide in 1942 as alternate names for nicotinic acid and nicotinamide, respectively, and encouraged their ...
Fanning may refer to: Fanning (bees), a behaviour of worker bees signalling an entrance to a hive; Fanning (firearms), a shooting technique in which one hand holds a revolver and the other hits the hammer repeatedly; Fanning (surname) Fanning friction factor, a dimensionless number used in fluid flow calculations; Fan dance, a dance art form
John Thomas Fanning (1837–1911) was an American architect and hydraulic engineer. His contribution to fluid mechanics and hydraulic engineering is in the Fanning friction factor which is used by engineers in the present age to calculate the frictional pressures losses in flows inside pipes.
