The effect of finite volume fraction of suspended particulate matter on axially symmetrical jet mixing of incompressible dusty fluid has been considered. Assuming the velocity and temperature in the jet to differ slightly from the surrounding stream, a perturbation method has been employed to linearize the nonlinear differential equation. The linear equations have been solved by using Laplace transformation technique. Numerical computations have been made to discuss the magnitude of the longitudinal perturbated fluid velocity. It is observed that increase in concentration parameter of dust particle reduces the magnitude of fluid velocity significantly.
