Consider steady flow of water through an axisymmetric garden hose nozzle (Fig. P9-38). 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 u z = 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.
