B.  Eulerian Method

The method was developed by Leonhard Euler.

This method is of greater advantage since it avoids the determination of the movement of each individual fluid particle in all details.

It seeks the velocity and its variation with time t at each and every location () in the flow field.

In Eulerian view, all hydrodynamic parameters are functions of location and time.

Mathematical representation of the flow field in Eulerian method:
