Unformatted text preview: settling velocities for two different grain sizes is 2 2 1 2 1 = r r v v where v 1 and v 2 are the velocities for grains of radius r 1 and r 2 respectively. Now with that result in mind consider the following problem. If a grain of radius 0.1 mm, suspended in a lake takes 10 days to settle to the lake bottom, how long would it take a grain of radius 1mm? Hand in before you leave today 37...
