**Abstract**

This paper deals with a steady flow of a viscous fluid of finite depth in a porous medium over a fixed horizontal, impermeable and thermally insulated bottom where as the other side is stress free and kept at a constant temperature with a constant heat source distributed uniformly in the flow region. Exact solutions of Momentum and Energy equations are obtained when the temperatures on the fixed bottom and on the free surface are prescribed. Flow rate ,Mean velocity , Temperature , Mean Temperature , Mean Mixed Temperature in the flow region and the Nusselt number on the free surface have been obtained. The cases of large and small values of porosity coefficient have been obtained as limiting cases. Further the cases of small depth(shallow fluid) and large depth (deep fluid) are also discussed. The results are illustrated graphically.
