An oblique flat surface model is used to simulate the rotating roil. The flow regions proposed by Landau and Levich is utilized in the analysis. The inertia force terms are included and a more realistic 2-dimensional boundary conditions for the free surface is used in this paper. Also, the solution is obtained by utilizing a refinement of integral method. The results are compared with available experimental data. It is shown that the prediction is sufficiently accurate over a wide range of capillary number, and better than the other existing results. The film thickness increase with respect to increasing capillary number up to a certain higher values from then then tendency Slows down and even decreases due to inertia effects.
