Derive the expression for the terminal velocity of a spherical particle falling in (a) a liquid if the drag force follows Equation Q2: F = 3rudu Equation Q2 %3D where: the drag force for a spherical particle (N) fluid viscosity (Pa s) particle diameter (m) particle velocity (m s) FD %3D -3 is dropped (b) into a vertical tube of glycerol, which has a viscosity of 0.6 Pa s and density 1200 kg m. The tube is 1.8 m long. Assuming the sphere attains terminal velocity instantly and follows Stokes' Law, how long does it take to reach the bottom of the tube? A spherical particle of diameter 600 um and density 3600 kg m c) Using diagrams, describe the two types of hindered settling.
