In a pipette analysis, 25 g of soil was dispersed in water, and the suspension was made to a volume 500 ml, The viscosity of water is 0.0012 SI units. Seven minutes after the commencement of sedimentation, 10 m/ of suspension was taken at a depth of 100 mm. The sampled volume was dried and found to have mass of 0.3 g and G = 2.70. Compute (a) Largest size of particle remaining in suspension 7 minutes after the commencement of sedimentation at a depth 100 mm. (b) The percentage of finer particles.
