  2. Gas constant - Wikipedia

    en.wikipedia.org/wiki/Gas_constant

    This disparity is not a significant departure from accuracy, and USSA1976 uses this value of R ∗ for all the calculations of the standard atmosphere. When using the ISO value of R , the calculated pressure increases by only 0.62 pascal at 11 kilometres (the equivalent of a difference of only 17.4 centimetres or 6.8 inches) and 0.292 Pa at 20 ...

  3. R (cross section ratio) - Wikipedia

    en.wikipedia.org/wiki/R_(cross_section_ratio)

    R is an important input in the calculation of the anomalous magnetic dipole moment. [1] Experimental values have been measured for center-of-mass energies from 400 MeV to 150 GeV. [2] R also provides experimental confirmation of the electric charge of quarks, in particular the charm quark and bottom quark, and the existence of three quark ...

  6. List of moments of inertia - Wikipedia

    en.wikipedia.org/wiki/List_of_moments_of_inertia

    Thin cylindrical shell with open ends, of radius r and mass m. This expression assumes that the shell thickness is negligible. It is a special case of the thick-walled cylindrical tube for r 1 = r 2. Also, a point mass m at the end of a rod of length r has this same moment of inertia and the value r is called the radius of gyration.

  7. Heat transfer coefficient - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer_coefficient

    R = Resistance(s) to heat flow in pipe wall (K/W) Other parameters are as above. [16] The heat transfer coefficient is the heat transferred per unit area per kelvin. Thus area is included in the equation as it represents the area over which the transfer of heat takes place. The areas for each flow will be different as they represent the contact ...

  9. Talk:R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/Talk:R-value_(insulation)

    R-values are about heat transfer by whatever means from one control volume to another. Jdpipe 01:59, 16 November 2008 (UTC) R value is defined by the engineering equation where it is used to calculate conductive heat transfer. The equation that uses R value definitely does not calculate thermal radiation heat transfer.
