  2. K factor (traffic engineering) - Wikipedia

    en.wikipedia.org/wiki/K_factor_(traffic_engineering)

    The K Factor also helps calculate the peak-to-daily ratio of traffic. K30 helps maintain a healthy volume to capacity ratio. [3] K50 and K100 will sometimes be seen. K50 and K100 will not use the 30th highest hourly traffic volumes but the 50th or 100th highest hourly traffic volume when calculating the K factor.

  3. K-factor (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/K-factor_(metallurgy)

    The K-factor is the bending capacity of sheet metal, and by extension the forumulae used to calculate this. [1] [2] [3] Mathematically it is an engineering aspect of geometry. [4] Such is its intricacy in precision sheet metal bending [5] (with press brakes in particular) that its proper application in engineering has been termed an art. [4] [5]

  4. K-factor (fire protection) - Wikipedia

    en.wikipedia.org/wiki/K-factor_(fire_protection)

    In fire protection engineering, the K-factor formula is used to calculate the volumetric flow 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.

  5. K-factor - Wikipedia

    en.wikipedia.org/wiki/K-factor

    K factor (crude oil refining), a system for classifying crude oil; K-factor (fire protection), formula used to calculate the discharge rate from a fire system nozzle; K-factor (metalurgy), formulae used to calculate the bending capacity of sheet metal; K factor (traffic engineering), the proportion of annual average daily traffic occurring in ...

  6. Elo rating system - Wikipedia

    en.wikipedia.org/wiki/Elo_rating_system

    The ICC compensates for this issue by assigning a lower K-factor to the established player if they do win against a new rating entrant. The K-factor is actually a function of the number of rated games played by the new entrant. Therefore, Elo ratings online still provide a useful mechanism for providing a rating based on the opponent's rating.

  7. Strain hardening exponent - Wikipedia

    en.wikipedia.org/wiki/Strain_hardening_exponent

    The strain hardening exponent (also called the strain hardening index), usually denoted , is a measured parameter that quantifies the ability of a material to become stronger due to strain hardening.

  8. Explosives safety - Wikipedia

    en.wikipedia.org/wiki/Explosives_safety

    A video on safety when using explosives in the workplace. Explosives safety refers to the practices taken during the use of explosives to prevent injury or death. Explosives include chemicals such as TNT or dynamite as well as other kinds of explosives, such as land mines, C-4s, and IEDs.

  9. Hazen–Williams equation - Wikipedia

    en.wikipedia.org/wiki/Hazen–Williams_equation

    The conversion factor k was chosen so that the values for C were the same as in the Chézy formula for the typical hydraulic slope of S=0.001. [9] The value of k is 0.001 −0.04. [10] Typical C factors used in design, which take into account some increase in roughness as pipe ages are as follows: [11]
