The viscosity of a fluid is to be measured by a viscometer constructed of two 5 ft-long concentric cylinders. The inner diameter of the outer cylinder is 6 inches. The gap between the two cylinders is 0.035 inch. and the gap is filled with fluid. The outer cylinder rotates at 250 rpm, and the torque is measured […]
