  2. Rankine scale - Wikipedia

    en.wikipedia.org/wiki/Rankine_scale

    The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit. [3] The symbol for degrees Rankine is °R [2] (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol. [4] [5]

    r* = 0.7: K = 3.953 W ⋅ m −1 ⋅ K −1 Soil B r = 0.8: K = 3.348 List [121] 268.15 ± 2K In this sample of two there is one very dirty kind of ice that conducts heat at nearly twice the rate of plain ice. *r ≡ The ratio of the water mass to the dried mass. Solder, Sn/63% Pb/37% 50 [122]

  4. Q10 (temperature coefficient) - Wikipedia

    en.wikipedia.org/wiki/Q10_(temperature_coefficient)

    The rate ratio at a temperature increase of 10 degrees (marked by points) is equal to the Q 10 coefficient. The Q 10 temperature coefficient is a measure of temperature sensitivity based on the chemical reactions.

  5. Scale-free network - Wikipedia

    en.wikipedia.org/wiki/Scale-free_network

    In a random network the maximum degree, or the expected largest hub, scales as k max ~ log N, where N is the network size, a very slow dependence. In contrast, in scale-free networks the largest hub scales as k max ~ ~N 1/(γ−1) indicating that the hubs increase polynomically with the size of the network.

  6. Fresnel equations - Wikipedia

    This becomes more obvious when the field is factored as E k e ik⋅r e −iωt, where the last factor contains the time-dependence. That factor also implies that differentiation w.r.t. time corresponds to multiplication by −iω. [Note 2] If ℓ is the component of r in the direction of k, the field can be written E k e i(kℓ−ωt).

  7. Kelvin - Wikipedia

    en.wikipedia.org/wiki/Kelvin

    It may be in plural form as appropriate (for example, "it is 283 kelvins outside", as for "it is 50 degrees Fahrenheit" and "10 degrees Celsius"). [ 57 ] [ 5 ] [ 58 ] [ 59 ] The unit's symbol K is a capital letter, [ 39 ] per the SI convention to capitalize symbols of units derived from the name of a person. [ 60 ]

  8. Bode plot - Wikipedia

    en.wikipedia.org/wiki/Bode_plot

    The Bode phase plot is the graph of the phase, commonly expressed in degrees, of the argument function ⁡ ((=)) as a function of . The phase is plotted on the same logarithmic ω {\displaystyle \omega } -axis as the magnitude plot, but the value for the phase is plotted on a linear vertical axis.

  9. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...
