  2. Boltzmann constant - Wikipedia

    en.wikipedia.org/wiki/Boltzmann_constant

    The characteristic energy kT is a term encountered in many physical relationships. The Boltzmann constant sets up a relationship between wavelength and temperature (dividing hc / k by a wavelength gives a temperature) with one micrometer being related to 14 387 .777 K , and also a relationship between voltage and temperature ( kT in units of eV ...

  3. kT (energy) - Wikipedia

    en.wikipedia.org/wiki/KT_(energy)

    kT (also written as k B T) is the product of the Boltzmann constant, k (or k B), and the temperature, T.This product is used in physics as a scale factor for energy values in molecular-scale systems (sometimes it is used as a unit of energy), as the rates and frequencies of many processes and phenomena depend not on their energy alone, but on the ratio of that energy and kT, that is, on ⁠ E ...

  4. Kilowatt-hour - Wikipedia

    en.wikipedia.org/wiki/Kilowatt-hour

    A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities.

  5. List of acronyms: K - Wikipedia

    en.wikipedia.org/wiki/List_of_acronyms:_K

    This list contains acronyms, initialisms, and pseudo-blends that begin with the letter K.. For the purposes of this list: acronym = an abbreviation pronounced as if it were a word, e.g., SARS = severe acute respiratory syndrome, pronounced to rhyme with cars

  6. Motor constants - Wikipedia

    en.wikipedia.org/wiki/Motor_constants

    The inverse relationship between force per unit current and of a linear motor has been demonstrated. To translate this model to a rotating motor, one can simply attribute an arbitrary diameter to the motor armature e.g. 2 m and assume for simplicity that all force is applied at the outer perimeter of the rotor, giving 1 m of leverage.

  7. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    This is an example of a linear free energy relationship as log(K a) is proportional to the standard free energy change. Hammett originally [ 51 ] formulated the relationship with data from benzoic acid with different substituents in the ortho - and para - positions: some numerical values are in Hammett equation .

  8. Binding constant - Wikipedia

    en.wikipedia.org/wiki/Binding_constant

    The binding constant, or affinity constant/association constant, is a special case of the equilibrium constant K, [1] and is the inverse of the dissociation constant. [2] It is associated with the binding and unbinding reaction of receptor (R) and ligand (L) molecules, which is formalized as:

  9. Mean effective pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_effective_pressure

    The mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement. [1]
