use cylindrical coordinates equations zero out all of the transient terms, take the limit as the density goes to a constant and div U goes to zero. mass equation will collapse to div U = 0 once I've calncelled. what do i do?

Can somebody provide a solution for this question? convert 3 dimensional unsteady compressible NS equations to axisymmetric 2 dimensional incompressible laminar form for a cylindrical pipe, then make a derivation of streamwise velocity profile u(r) using the appropriate boundary conds. thanks
