Question

Compute the settling velocity for the following particles: very coarse sand ( diameter = 1.5 mm ) , (diameter=1.5 mm), medium sand (0.4 mm), very fine sand (0.075 mm), and clay (0.001 mm). Estimate the time for each particle to fall 6 in. in water.

Assume: SG: coarse sand = 2.65, medium sand = 2.67, fine sand = 2.70, clay = 2.8 & water temperature = 60°F

Note:The solution someone posted earlier today is wrong.
