            1.8  For  radial flow of  an incompressible Newtonian fluid between two  parallel
           circular disks of radius R2  as shown in Figure 1.4, the steady-state velocity distri-
           bution is (Bird et al., 1960)





           where R1  is the radius of  the entrance hole. Determine the volumetric flow rate.
