Determine the terminal velocity for particles of sphalerite (s.g. = 4.0) in a gravity settler filled with liquid with density = 998 kg/m3. The diameter of the particles is 2.5 x 10-5 m and the viscosity of the fluid is 0.9 cP. = * K = De [gpp(p-1)] Pp u2 Pp)]1/3 = = g = gravity 9.8 m/s2 p = s.g. x 1000 (kg/m3) 1 Pa = kg/ms? K = settling constant (dimensionless) Viscosity, Mp=0.9 CP (centipoise) 1 centipoise = 0.01 Poise = Dp = 2.5 x 10-5 = 1 Solve for constant K, then use the K to confirm the Region assumed for this system. Use conversion and be careful with your units when you do your calculations.
