Class 11 Physics Mechanics Mechanical Properties of Fluids
A powder comprising particles of various sizes is stirred up in a vessel filled to a height of 10 cm with water. Assuming the particles to be spherical, find the size of the largest particle that will remain in suspension after 1 h (density of powder = 4 , viscosity of water = 0.01 poise). 
Solution: Terminal velocity of the largest particle which is just about to settle at the bottom of the
Vessel is 
 
Let r be the radius of that particle. Then 

where   
After solving, we get r = 2.0 m.
