1. The problem statement, all variables and given/known data A falling sphere viscometer measures the viscosity of a liquid from the terminal velocity of a tiny, falling sphere. One such device determines that a tiny sphere of radius 46 μm falls through a liquid with a terminal velocity of 2.5 mm/s. If the density of the sphere is 4171 kg/m3 and the density of the liquid is 718 kg/m3 what is the shear viscosity of the liquid? r sphere = 46 μm ρ sphere = 4171 kg/m^3 ρ liquid = 718 kg/m^3 v = 2.5 mm/s 2. Relevant equations F = 6πηrv Continuity: ρAv 3. The attempt at a solution Would I be able to find the Force by using the equation: F = ρAv2 which is just the continuity equation times velocity?
