In this paper, we consider flow of thin liquid film on an inclined solid surface with an inclination angle . We use the Navier-Stokes equations to obtain equations that govern such flow .We solve these equations analytically with an appropriate boundary conditions to determine the thickness of the film for different values of the inclined angle .

In this paper, we consider steady incompressible viscous flow in a symmetric thin liquid film on an inclined surface with angle b in two dimensions with no inertia force. The surface of the film is taken to be real that is there is no shear stress on the liquid surface. We found the differential equations that govern the flow. We solve these equations numerically by using Rang Kutta method.
