Methods of describing fluid motion Fluid motion is described by two methods. (1) Lagrangian Method In the Lagrangian method, a single fluid particle is followed during its motion and its velocity, acceleration, density, etc., are described. (2) Eulerian Method In case of Eulerian method, the velocity, acceleration, pressure, density etc., are described at a point in flow field . This method is commonly used in fluid mechanics.
