Abstract : The problem of flow of an elaatico-viscous liquid past a hot vertical porous flat plate has been considered by taking into account the effect of free convection when a body force 'g' acts in a direction opposite to that in which flow takes place. Numerical calculations have been made to study the effect of free convection and elasticity of the fluid on the fluid velocity. The fluid velocity and the skin-friction both increase with the Grashof number. The skin-friction is not affected by the elastic elements. The fluid velocity increases with the relaxation time but decreases with the increase in retardation time.
