- Questions (1) With the Brookfield viscometers, why each spindle must be calibrated and used in the specified container to obtain the "true" viscosity of the sample fluid?arrow_forwardEarrow_forwardTutorial Problem #3. As we discussed in lecture, a concentric cylinder viscometer is often used to measure the viscosity (μ) of Newtonian fluids. As shown in the accompanying figure, the outer cylinder (with radius Ro) remains stationary while the inner cylinder (with radius R₁) rotates at an angular velocity of w (rev/min) and the torque (T) required to rotate the inner cylinder is measured. Outer Cylinder Fluid Inner Cylinder T ω R₁ R a. Starting from Newton's law of viscosity, derive the correct equation that is used to calculate u in μ terms of w, T, Ro, R₁ and € (the height of the fluid in the gap between the two cylinders). Because the radial distance between the cylinders (i.e Ro - R₁) is quite small, you can assume that the velocity profile of the fluid varies linearly with respect to distance between the cylinders. HINT #1: Torque is the required force multiplied by the moment arm (which is R¡ in this case) HINT #2: Multiply the angular velocity by the circumference of the…arrow_forward
