Fluid flows in layers and most of all each layer is constituted of infinite number of particles. Assuming the flow is laminar, this topic is being presented to analyze particle motion mathematically applying Lagrangian and Eulerian methods. Lagrangian method deals with particles as a moving body and Eulerian method focusing on observing condition of a fixed point inside fluid passed by moving particles of the flow. As a matter of fact, there are three major subjects in considering the discussion of the topic and they are flow velocity, pressure change, and density variation. The last two subjects are quite difficult to solve with mathematics model and the first subject is not tedious thing to carry out mathematically with the two mentioned methods. A simple simulation program has been generated to trace particles coordinate along with their motion and velocity changing in the fixed point position. The results are being given as the expression of different values of coordinates in Lagrangian system and variation of velocity of particles in Eulerian system. It was found that the new position of particles is a function of time and original position.
