The purpose of this paper is to present the effect of variable viscosity on unsteady laminar boundary layer flow and the heat transfer of a fluid over a stretching sheet that is studied numerical manner. It is expected that the unsteadiness is noticed by time dependent stretching velocity and a sudden growth in surface temperature. This is done by using similarity solutions of partial differential equations corresponding to the momentum and energy equations that are converted into highly non-linear ordinary differential equations. Numerical solutions of these equations are obtained with the help of an implicit finite difference scheme along with a quasi-linearization technique. It shows an increase in the unsteady parameter whenever skin friction and heat transfer coefficients increase, while fluid velocity and temperature keep decreasing with an increase in temperature dependent viscosity. Similar trends have been obtained for different Prandtl number for any fixed viscosity and unsteady parameter.
