Consider steady flow of water through an axisymmetric garden hose nozzle (Fig. P9–29). The axial component of velocity increases linearly from u_{z, entrance} to u_{z, exit} as sketched. Between z = 0 and z = L, the axial velocity component is given by uz = u_z,entrance + [(u_z,exit – u_z,entrance)/L]z. Generate an expression for the radial velocity component u_r between z = 0 and z = L. You may ignore frictional effects on the walls.
