K factor (traffic engineering) In transportation engineering, the K factor is defined as the proportion of annual average daily traffic occurring in an hour. [1] This factor is used for designing and analyzing the flow of traffic on highways. K factors must be calculated at a continuous count station, usually an "automatic traffic recorder ...
In fracture mechanics, the stress intensity factor ( K) is used to predict the stress state ("stress intensity") near the tip of a crack or notch caused by a remote load or residual stresses. [1] It is a theoretical construct usually applied to a homogeneous, linear elastic material and is useful for providing a failure criterion for brittle ...
A k-factor of a graph is a spanning k-regular subgraph, and a k-factorization partitions the edges of the graph into disjoint k-factors. A graph G is said to be k-factorable if it admits a k-factorization. In particular, a 1-factor is a perfect matching, and a 1-factorization of a k-regular graph is a proper edge coloring with k colors. A 2 ...
K-factor (aeronautics), the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter. K-factor (centrifugation), relative pelleting efficiency of a given centrifuge rotor. K factor (crude oil refining), a system for classifying crude oil.
K-factor. K-factor is a ratio of the location of the neutral line to the material thickness as defined by t/T where t = location of the neutral line and T = material thickness. The K-factor formula does not take the forming stresses into account but is simply a geometric calculation of the location of the neutral line after the forces are ...
K-factor (fire protection) In fire protection engineering, the K-factor formula is used to calculate the volumetric flow rate rate from a nozzle. Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
In viral marketing, the K-factor can be used to describe the growth rate of websites, apps, or a customer base. The formula is roughly as follows: [1] (e.g. if each new customer invites five friends, i = 5) (e.g. if one in five invitees convert to new users, c = .2) This usage is borrowed from the basic reproduction number in the medical field ...
The USLE was developed from erosion plot and rainfall simulator experiments. The USLE is composed of six factors to predict the long-term average annual soil loss (A). The equation includes the rainfall erosivity factor (R), the soil erodibility factor (K), the topographic factors (L and S) and the cropping management factors (C and P). The ...
