6.96 An incompressible Newtonian fluid flows steadily between two infinitely long, concentric cylinders as shown in Fig. P6.96. The outer cylinder is fixed, but the inner cylinder moves with a longitudinal velocity V, as shown. The pressure gradient in the axial direction is - Apll. For what value of V, will the drag on the inner cylinder be zero? Assume that the flow is laminar, axisym- metric, and fully developed. Fixed wall Figure P6.96
