ABSTRACT	In this paper we examined a complex potential solution for impinging jets, from a hydrodynamic perspective. The physical characteristics of the flow field were illustrated using a stream line diagram, velocity contour diagram and static pressure contour diagram.The same problem was then solved numerically. A series of interpolation and differentiation procedures based on the Lagrange interpolation formula were applied systematically to solve the problem. Two grid systems were tested, a coarse and a fine system. The numerical results were compared with the analytical results to evaluate accuracy. Convergence of solution and computing time were also evaluated. The free stream line was successfully described using parameters.
