Uniformity coefficient definition
Uniformity coefficient means a value which is the ratio of D60 to D10 where D60 is the soil diameter of which 60 percent of the soil weight is finer and D10 is the corresponding value at 10 percent finer. (A soil having a uniformity coefficient smaller than 4 would be considered "uniform" for purposes of this regulation.)
Uniformity coefficient means a number obtained by dividing that size of sand in millimeters of which 60% by weight is smaller, by that size of sand in millimeters of which 10% by weight is smaller.
Uniformity coefficient means a numeric quantity calculated by dividing the size of the sieve opening which will pass sixty percent of a sample by the size of the opening which will pass ten percent of the sample on a weight basis. Symbolically this is depicted as d60/d10 = Uc.

Uniformity coefficient means the ratio of the sieve size that will retain 40 percent of the aquifer materials to the effective size.
Uniformity coefficient means the number representing the degree of homogeneity in the distribution of particle sizes of filter sand or other granular material. The coefficient is calculated by determining the D60/D10 ratio where D10 and D60 refer to the particle diameter corresponding to the 10 and 60 percentile of the material which is finer by dry weight.
Uniformity coefficient means a ratio of the sieve-size opening that will pass sixty per cent of a representative sample of the filter material divided by the sieve-size opening that will pass ten per cent of the material.
Uniformity coefficient means a numeric quantity calcula- ted by dividing the size of the sieve opening which will pass sixty percent of a sample by the size of the opening which will pass ten
