Abstract
An unsteady boundary layer flow of viscous incompressible fluid over a stretching plate has been considered to solve heat flow problem with variable thermal conductivity. First, using similarity transformation, the velocity components have been obtained, and then the heat flow problem has been attempted in the following two ways: 1) prescribed stretching surface temperature (PST), and 2) prescribed stretching surface heat flux (PHF) Flow and temperature fields have been analyzed through graphs. The expressions for skin friction and coefficient of convective heat transfer Nusselt number in PST and PHF cases have been derived.

Due to number of applications in industrial manufacturing process, the problem of boundary layer flow past a stretching plate has attracted considerable attention of researchers during the past few decades

From Equation (4.5), we note that the heat transfer takes place in two parts according to 0 and 0
Summary
Due to number of applications in industrial manufacturing process, the problem of boundary layer flow past a stretching plate has attracted considerable attention of researchers during the past few decades. Examples of such technological process are hot rolling, wire drawing, glass-fiber and paper production. Naseem Ahmad and Kavita Marwah [22] studied boundary layer flow of Walters Liquid B Model with heat transfer for linear stretching plate with variable conductivity numerically. In almost all the problems of stretching sheet with heat transfer where closed form solution is obtained, the thermal conductivity of liquid has been taken constant. Both the parts mean temperature and temperature due to variable thermal conductivity have been analyzed thoroughly for some new recommendations
