The O S equation is solved numerically for pipe Poiseuille flow by using the Chebyshev polynomial method. All the eigenvalues are proved to be negative and it is shown that the circular Poiseuille flow is stable with axisymmetric infinitesimal distrubances. The numerical results are of high accuracy.
