Unformatted text preview: 1. (Viscous stress  20 pts) The viscosity of liquids can be measured through
the use of a rotating viscometer of the type illustrated in the figure. In this
device the outer cylinder is fixed and the inner cylinder is rotated at a known
angular velocity, ω. The torque T required to develop ω is measured and the
viscosity, µ, is calculated from these two measurements. Develop an
equation relating T, ω, µ, l, Ri, and Ro. Neglect end effects and assume the
velocity distribution in the gap is linear. liquid
