Which of the following method is used exclusively in fluid mechanics?

A)
Eulerian method
B)
Lagrangian method
C)
Both Lagrangian and Eulerian methods
D)
Neither Lagrangian nor Eulerian method

Correct Answer : Option (A) :   Eulerian method

Explanation : In Fluid Mechanics, the matter of concern is the general state of motion at various points in the fluid system (as in Eulerian approach) rather than the motion of each particle (as in Lagrangian approach). Hence, the Eulerian method is extensively used in Fluid Mechanics.
