Which of the following fluid forces are not considered in the Navier-Stoke's equation ?
Correct answer: D. Turbulent forces
- A. Gravity forces
- B. Viscous forces
- C. Pressure forces
- D. Turbulent forces
Explanation
The Navier-Stokes equation explicitly includes pressure, viscous, and body forces such as gravity. Turbulence is not a separate fundamental force term, although turbulent effects may be represented through modelling after averaging.
