Fluid viscosity can be measured by a rotating-cylinder viscometer, which consists of two concentric cylinders with a uniform gap between them. The liquid to be measured is poured into the gap between the two cylinders. For a particular liquid, the inner cylinder rotates at 2,000 rpm, and the outer cylinder remains stationary and measures a torque of 1.50 N ∙ m. The inner cylinder diameter is 5.0 cm, the gap width is 0.02 cm, and the liquid fills up to a height of 4. 0 cm in the cylindrical gap. Determine the absolute viscosity of the liquid in N · sec/m2.
