Considering the variation of properties depending upon temperature, the auther calculated heat transfer and skin friction for a heated flat plate in longitudinal flow of water. The differential equations for laminar forced convection are solved by means of perturbation theory, using the Pohlhausen's solution for constant properties as 0 approximation. It is assumed that (1) density and specific heat are constant ; (2) viscosity varies in proportion to T^<-6>, where T is absolute temperature ; and (3) thermal conductivity varies in proportion to T^<m>, where m varies with temperature of general flow. Fricton factor and Nusselt's number are given for the value of (T_0-T_1)/T_1,where T_0 and T_1 are the absolute temperature of plate and general flow, respectively.
