A cylinder with a diameter of 0.2 m and a length of 1.0 m is
arranged concentrically inside a pipe whose inside diameter is
0.206. If there is an oil film between the cylinder and the tube
with S = 0.92 and a kinematic viscosity of 6.0 Stokes. Determine
the force needed to move the cylinder at a constant speed of 1.0
m/s (neglect the weight of the cylinder).
