Abstract: A Fluid Structure Interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow, FSI are essential consideration in the design of many engineering systems, e.g., aircrafts, nuclear and piping system. The governing equation of transverse vibration for pipe conveying fluid was derived from momentum equation for moving control volume and the continuity equations, the coupling between the fluid and pipe forces was considered. The equation derived was compared with those from the previous researchers for validation of the proposed equation. The FSI water hammer equation coupled with proposed equation was presented and the system was solved to find the transient pressure and the displacement associated with it. The Method of Characteristic (MOC) and Finite Difference Method (FDM) were used in the solution. In this study, a numerical application was done for the proposed equation, the present results reveal acceptable with previous researchers’ results. The pipe length between the supports has a significant affect on the pipe displacement. The displacement to the pipe length ratio when succeeds (0.5%) or more has effect on the fluid pressure and velocity.
