A cylinder of 125mm radius rotates concentrically inside a fixed cylinder of 130mm radius. Both cylinders are 300mm long. Determine the viscosity (in Pa-s) 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 2n radians/sec.
