Question

The viscosity of a fluid is to be measured by the viscometer
constructed of two 80 cm long cylinders. The outer diameter of the
inner cylinder is 15 cm, wd the gap between the two cylinders is 1
mm. The inner cylinder is rotated at 300 rpm, and the torque is
measured to be 0.8 N-m. Determine the viscosity of the fluid.

Answer 1

Answer:

The viscosity of a fluid is to be measured by an 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.
