The depth of water is 2×10−2m. What is the diameter of the largest particles remaining in suspension one hour later? Density of pollen =1.8×103 kgm^-3 viscosity of water =1×10^−2 poise and density of water =1×10−5 kg m^−3

A powder comprising particle of various sizes is stirred up in a vessel filled to a height of 10cm with water. Assuming the paticle to be spherical find the size of the largest particle that will remain in suspension after 1 h (density of powder =4 g/cm3
