(20 points) The inner cylinder is submerged as shown in figure 1 in a fluid with viscosity µ. The gaps between the inner cylinder and outer cylinder are δ and no fluid is on top of the inner cylinder. The outer cylinder rotates with an angular speed ω. The torque required to keep the inner cylinder stationary is T and the velocity distribution in the gap is linear.
