In this study, it was formulated the boundary-value-problem (BVP), comprising partial differential equations (PDEs), of steady flow for plane, laminar jet of a micropolar fluid. A new similarity transformation/solution was derived which is valid not only for the Newtonian fluids but also for the micropolar fluids. Obviously, this transformation will be transformed the PDEs into the ordinary differential equations (ODEs). These ODEs were solved numerically by the finite difference method. The obtained results were compared with existing results [1, 12] for the Newtonian fluids. The comparison was favourable. As the aciculate particles in a micropolar fluid can rotate without translation, the micropolarity effects must have influence on fluid-speed, microrotation, stresses, couple stresses and discharge. This influence was highlighted in the present study. If viscosity coupling parameter K1 (being the measure of micropolarity) increases then microrotation, fluid-flux, stresses and couple stresses intensify in the vicinity of the jet along y-direction. The fluid-flux, , for a fixed value of K1 and for the micropolar as well as Newtonian fluids. In addition, the stress and the couple stress tensors are non-symmetric.
