Question

Euler's equation of motion is a statement of

• A. linear momentum conservation for the flow of an inviscid fluid
• B. mass conservation
• C. energy conservation
• D. linear momentum conservation for a real fluid

Answer 1

Answer:

A. linear momentum conservation for the flow of an inviscid fluid

Euler's equation of motion relates velocity, pressure, and density of a moving, non-viscous, homogeneous, and incompressible fluid. It is based on the conservation of linear momentum for a flow with no external forces except gravity and pressure. The integration of the equation gives Bernoulli's equation in the form of energy per unit weight of the fluid.
