Question

The fluid forces considered in the Navier-Strokes equation are

• A. Gravity, pressure and viscous
• B. Gravity, pressure and turbulent
• C. Pressure, viscous and turbulent
• D. Gravity, viscous and turbulent

Answer 1

Answer:

A. Gravity, pressure and viscous

The Navier-Stokes equation describes the motion of viscous fluid substances by applying Newton's second law to fluid motion. The equation assumes that the stress in the fluid is the sum of a diffusing viscous term and a pressure term, which describes the viscous flow. The fluid forces considered in the equation are gravity, pressure, and viscous forces.
