Abstract :The Lagerstrom’s equation has been solved by an approximate technique combining both homotopy perturbation and variational iteration method. By this technique the solution of Lagerstrom’s equation can be determined for viscous flow past a solid at low Reynolds number where a significance mater is the occurrence of logarithmic term. In this technique ExpIntegralEi function has been used for simplifying the calculation. The results have been calculated by this technique shows a good agreement with those obtained by numerical method.Keywords : Lagerstroms equation, ExpIntegralEi, Homotopy perturbation method
