Explain the term Stokes flow and terminal velocity. Show that a spherical particle with Stokes flow has a terminal velocity given by u=d²g(ps-pi)/18μ Go on to show that Cp-24/R For spherical particles, a useful empirical formula relating the drag coefficient and the Reynold's number is 24 6 + Re 1+√R. Given pf = 1000 kg/m³, μ= 1 cP and p. 2630 kg/m³ determine the maximum size of spherical particles that will be lifted upwards by a vertical stream of water moving at 1 m/s. CD = +0.4 If the water velocity is reduced to 0.5 m/s, show that particles with a diameter of less than 5.95 mm will fall downwards. Explain the term Stokes flow and terminal velocity.
