bbappsrv.pmu.edu.sa Exercise #1: The viscosity of a fluid is to be measured by a viscometer constructed of two 75-cm- long concentric cylinders. The outer diameter of the inner cylinder is 15 cm, and the gap between the two cylinders is 0.12 cm. The inner cylinder is rotated at 200 rpm, and the torque is measured to be 0.8 N.m. Determine the viscosity of the fluid. Exercise #2: 200 rpm 0.12 cm Fluid Stationary cylinder
