The present study narrates the heat transfer of unsteady non-Newtonian Casson fluid flow with Newtonian heating and variable velocity. The governing equations of the flow are converted into dimensionless form using non-dimensionless variables. Exact solutions are obtained for temperature and velocity of the fluid with the aid of Laplace transform technique. For better understanding of the problem effect of different critical parameters on the flow have been analyzed graphically. It is observed that increment in Newtonian heating parameter raises the temperature of the fluid. Comparative results of skin friction of the present work with the earlier ones are depicted in tabular form which are seen to be in good agreement.
