4. A cylindrical rod of radius KR moves axially with velocity vo along the axis of a cylindrical cavity of radius R as seen below. The pressure at both ends of the cavity is the same, so that the fluid moves through the annular region solely because of the rod motion. Assume the fluid is incompressible and isothermal and the flow is fully-developed and laminar. a) Find the velocity distribution in the narrow annular region, assuming equation 2.4-1 applies. b) Find the mass rate of flow through the narrow annular region.
