  3. Grain size - Wikipedia

    en.wikipedia.org/wiki/Grain_size

    Size ranges define limits of classes that are given names in the Wentworth scale (or Udden–Wentworth scale named after geologists Chester K. Wentworth and Johan A. Udden) used in the United States. The Krumbein phi (φ) scale, a modification of the Wentworth scale created by W. C. Krumbein [1] in 1934, is a logarithmic scale computed by the ...

    F=f(Sh, A, R, Sp, T) where f denotes a functional relationship between these terms and where Sh denotes the shape, Sp the sphericity and T the micro-scale surface texture. [ 2 ] An example of this practical use has been applied to the roundness of the grains in the Gulf of Mexico in order to observe the distance from the source rocks.

    This placed the JMA scale among non-Cancani macroseismic scales, distinguishing it from those belonging to the 12-degree Cancani family, such as the Modified Mercalli intensity scale or the European macroseismic scale. [16] Levels 5 and 6 were subdivided into "lower" and "upper," creating a 10-level scale.

    Therefore, general requirements for an effective TBC can be summarized as needing: 1) a high melting point. 2) no phase transformation between room temperature and operating temperature. 3) low thermal conductivity. 4) chemical inertness. 5) similar thermal expansion match with the metallic substrate. 6) good adherence to the substrate.
