In this paper, we examine the hydromagnetic boundary layer flow and heat transfer characteristics of a laminar nano liquid film over an unsteady stretching sheet is presented. The highly nonlinear partial dierential equations governing flow and heat transport are simplified using similarity transformation. The analytical solutions of the resulting ODEs are obtained for some special case of nano liquid film using hypergeometric power series functions, and from which the analytical solutions of the original problem are presented. The influence of pertinent parameters such as the magnetic parameter, the solid volume fraction of nanoparticles and the type of nanofluid on the flow, heat transfer, Nusselt number and skin friction coefficient is discussed analytically.
