    en.wikipedia.org/wiki/Normalized_number

    In many computer systems, binary floating-point numbers are represented internally using this normalized form for their representations; for details, see normal number (computing). Although the point is described as floating , for a normalized floating-point number, its position is fixed, the movement being reflected in the different values of ...

    en.wikipedia.org/wiki/Izbash_formula

    The Izbash formula is a mathematical expression used to calculate the stability of armourstone in flowing water environments. For the assessment of granular material stability in a current, the Shields formula and the Izbash formula are commonly employed. The former is more appropriate for fine-grained materials like sand and gravel, whereas ...

    However, if the current is a time-varying function, I(t), this formula must be extended to reflect the fact that the current (and thus the instantaneous power) is varying over time. If the function is periodic (such as household AC power), it is still meaningful to discuss the average power dissipated over time, which is calculated by taking ...

    en.wikipedia.org/wiki/Mach_number

    If the speed of sound is not known, Mach number may be determined by measuring the various air pressures (static and dynamic) and using the following formula that is derived from Bernoulli's equation for Mach numbers less than 1.0. Assuming air to be an ideal gas, the formula to compute Mach number in a subsonic compressible flow is: [8]
