(2) A circular cylinder shaft of 86 mm radius and 0.1 m length rotates coaxially inside a fixed cylinder of the same length and 90 mm radius. Glycerin (= 1.49 kg /ms) fills the space between the cylinders. A torque of 0.1 Nm is applied to the shaft. Find the constant velocity obtained by the surface of the shaft (in m/s), the rotational speed (in rpm) and the power dissipated by the fluid resistance [58 mm/s, 6.4 rpm] (2) A circular cylinder shaft of 86 mm radius and 0.1 m length rotates coaxially inside a fixed cylinder of the same length and 90 mm radius.
