WebbTARGET Filter Sand is suitable for many rapid and slow filtration systems. The washed feedstock is dried, to sterilize the materials, then sized to meet effective size and uniformity coefficient specifications. Rigorous quality control testing, during production, assures that the final product meets the requirements of the American WebbDesign a circular rapid sand filter of depth 1.2 meters with a sand uniformity coefficient of 1.3. The gravel depth should be 30% of sand depth. Design should also include weight of sand and gravel requirement. Assume the density of sand and gravel is typically around 1500 kg/m3.

Webbc) Sand with an effective size of 0.45 mm and uniformity coefficient of 1.35 is required. Available sand has an effective size of 0.55 mm and uniformity coefficient of 2.55. Which fraction of the sand would be usable and which fractions smaller and larger than required need to be discarded? Solution WebbThe uniformity coefficient (Cu) is defined as the ratio of D60 to D10. A value of Cu greater than 4 to 6 classifies the soil as well graded. When Cu is less than 4, it is classified as poorly graded or uniformly graded soil. … WebbUniformity Coefficient (C u) which is a measure of the uniformity of grain size in the soil and is defined as the ratio of the 60% finer size (D 60) to D 10. that is Cu = D60 D10 … google chrome官网入口
