Find all correct descriptions about the fluid flow
A There are two ways to describe the fluid flows: Lagrangian and Eulerian descriptions
B Individual fluid particles positions velocities, etc. are described as a function of time in the Lagrangian description
C The physical laws, such as Newton's laws and conservation of mass and energy, apply directly to each particle in the Lagrangian description
D Lagrangian descriptions are rarely used in fluid mechanics, and the Eulerian descriptions are usually preferred to use in the fluid mechanics
E Each field in the Eulerian descriptions is expressed as a function of space and time pressure velocity, acceleration, etc.
F Some translation or reformulation of the physical laws, such as Newton's laws and conservation of mass and energy, is required for use with a Eulerian description.
