CE616: Assignment 03

Due Date: Friday, 12 September 2014

1. The Stokes Law (C d = 24/Re) is valid for  Re ≤ 0.1. Estimate the maximum size of a spherical

quartz particle for which the Stokes Law will hold. What will be the corresponding settlingvelocity. Make necessary assumptions and state them.

2. Using the C d  vs Re  relationship given in the class, plot the rescaled relationship,  C ∗

d  vs Re, for

0.1 ≤ Re =  ρV d/µ
