The thin film flow of a power law fluid on a vertical cylinder for a lift and a drainage problem is studied. The goverming nonlinear differential equations have been derived from the continuity, momentum and constitutive equations. The resulting equations are then solved using binomial series method. Series solutions have been obtained for velocity, volume flow rate and average velocity in both cases. The graphical results for velocity profile is discussed and examined for different parameters of interest. Key words: Thin film flow, power law fluid, binomial series method.
