    The motion of fluid can be described by an expression representing the location of fluid particle in space at different times. This enables the determination of the magnitude and direction of velocity and acceleration in the flow at any time.
    There are two methods of describing fluid fluid motion:
    1. Lagrangian method
    2. Eulerian method
    In Lagrangian method, the observer concentrates on the movement of single particle in the fluid flow. Whereas in Eulerian method, the observer remains stationary and observes changes in the fluid parameters at a particular point in the fluid flow.
