text: A self-similar solution exist for the problem posed. The self-similar variables are
  Then the boundary layer equation reduces to
  with boundary conditions . If  is a solution, then  is also a solution. A particular solution which satisfies the condition at  is given by
  The constant  can be evaluated from the momentum condition,
  Thus the solution is
  Unlike the momentum flux, the volume flow rate in the  is not constant, but increases due to slow entrainment of the outer fluid by the jet,
  increases linearly with distance along the axis. Schneider flow describes the flow induced by the jet due to the entrainment.
