We performed the theoretical researches, in regard to heat transfer at laminar boundary layer, in the case of the flat plate with temperature gradient on its surface that was in the forced convection, by considering the fluid was non-compressive gas. At first, we obtained the exact solution and next the approximate solutions to be able to show the out-line of influences of many elements on heat transfer plainly. In both solutions, we assume that T_1-T_0=A_x^m, where T_1 and T_0 are temperatures of themain flow and that of the surface respectively, and x is the distance from the front edge of plate in the flowing direction. We calculated on the many cases by changing m values, of m and Prandtl's Numbers. And it is shown that value of the coefficient of surface hea transfer in the case of m=0.5 is 40% larger, and in the case of m=1 it is 60% larger, than that of in case of m=0.
