) The viscosity of a fluid is to be measured by a viscometer constructed of two 75 cm long concentric cylinders (shown in Fig. 1). 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. Assuming a linear velocity profile in the fluid film, determine the viscosity of the fluid.
