Question: A viscometer consists of two concentric cylinders, 10.20cm and 10.60cm in diameter, A particular liquid fills the space between them to a depth of 12.0cm.

A viscometer consists of two concentric cylinders, 10.20cm and 10.60cm in diameter, A particular liquid fills the space between them to a depth of 12.0cm. The outer cylinder is fixed, and a torque of 0.024m N keeps the inner cylinder turning at a steady rotational speed of 62 rev/min. What is the viscosity of the liquid?
