Lubricants

Lubricant can be expressed as the substance that is applied among surfaces to control the wear and tear and improve performance. Lubricants play an essential part in the safety of machinery components like gears, shaft, linkage, cam, clutches, and many others. The quantities which affect the amount of lubricant are temperature, surrounding conditions, speed of the components, and many more.

A viscometer constructed of two 30-cm-long concentric cylinders is used to measure the viscosity of a fluid. The outer diameter of the inner cylinder is 9 cm, and the gap between the two cylinders is 0.18 cm. The inner cylinder is rotated at 250 rpm, and the torque is measured to be 1.4 N⋅m. The viscosity of the fluid is (a) 0.0084 N⋅s/m2 (b) 0.017 N⋅s/m2 (c) 0.062 N⋅s/m2 (d ) 0.0049 N⋅s/m2 (e) 0.56 N⋅s/m2
The viscosity of a fluid placed in a gap of two cylinders is measured with the apparatus given in the figure. The diameter of the inner cylinder rotating at 300 revolutions per minute is 20 cm and its height is 90 cm. The distance between the two cylinders is 1 mm. Find the dynamic viscosity of the fluid as the moment applied to the rotating cylinder is measured as 2Nm. The friction on the lower surface of the rotating roller is neglected.
