The problem of determining the theoretically justified method of considering the natural shape of mineral grains in the calculations of their motion velocity in liquid media, especially their falling under the influence of the external mass force, in particular the force of gravity, has not been successfully solved so far. The presented paper shows a possibility of increasing the accuracy of calculations of this velocity with the use of the well-known formulas, discussed in the paper introduction, by means of the appropriate introduction of two different grain shape coefficients into them.
