The settling velocity of an object is a function of particle density and size and can be determined by Stokes's Law.

A) Calculate the settling speed for the bacterial cell with a diameter of 1, 2 and 50µm , with a density of 1.4 g cm^-3, and a viscosity of 0.01 g cm^-1s^-1. Assume freshwater at 20 ˚C.

B) Using the settling velocity calculated in part a, calculate the length of the number of days it would take to reach the bottom of Lake Victorian (84m)?

A settling chamber is measuring 6 meters in length, 3 meters in width, and 1.5 meters in height. The air stream flowrate entering the chamber is 17 m3/s, and the average particle size (diameter) is 65 micrometers. Assume a particle density of 1800 kg/m3 and that Stokes law applies. Some properties of air: Atmospheric pressure = 101.4 kPa = 14.7 psi Air density = 1.2 kg/m3. Air viscosity = 1.85x 10^-5 Pa.s. the air stream horizontal velocity in the chamber...

In addition to the buoyant force, an object moving in a liquid experiences a linear drag force Fdrag = (bv, direction opposite the motion), where b is a constant. For a sphere of radius R, the drag constant can be shown to be b = 6πηR, where η is the viscosity of the liquid. Consider a sphere of radius R and density ρ that is released from rest at the surface of a liquid with density ρf. a. Find an...
