A cylinder of 125 mm radius rotates concentrically inside a fixed cylinder of
130 mm radius. Both cylinders are 300 mm long. Determine the viscosity of the
liquid which fills the space between the cylinders if a torque of 0.88 N-m is
required to maintain an angular velocity of 2 rad/sec. Assume the velocity
gradient to be a straight line.
