3) The viscosity of the Newtonian fluid with a density of 650 kg/m3 is determined with a viscometer as shown in the figure below. The required torque (T =F.r) applied to the inner cylinder (ri = 4 cm) to rotate with an angular velocity of 6 rad/s is 3x10-7 Nm. If the velocity distribution in the clearance between the cylinders is linear, a) Find the viscosity (uo) of the fluid b) Find the shear stress on the side surfaces in the viscometer if the viscosity varies according to u = Ho (1-r/r2) where r2 = r+2 (cm) due to heating during rotation. %3D
