The flow of unsteady incompressible two dimensional system flow of a thin liquid films with negligible inertia is investigated. Continuity equation and Navier-Stokes equations are used to obtain the equation that governs this type of flow. 
 

In this paper we have investigated viscous flow in symmetric thin liquid films which are inclined by an inclination angle  to the horizontal for an incompressible liquids in two dimensions with no inertia force. We use the (Navier-Stocks) equations and we obtain equations that govern such flow and we solved these equations by numerical methods to obtain the thickness of the film.
