The effect of finite volume fraction of suspended particulate matter on axially symmetrical jet mixing of incompressible dusty fluid has been considered. Here we are assuming the velocity and temperature in the jet to differ only slightly from that of surrounding stream, a perturbation method has been employed to linearize the equations  which have been solved by using Laplace transformation technique. Numerical computations have been made to find the solutions of the longitudinal perturbated fluid velocity and longitudinal perturbated particle velocity.
