Navier-Stokes equation is useful in the analysis of _____________ fluid flow problems?
Correct answer: B. Viscous
- A. Non-viscous
- B. Viscous
- C. Turbulent
- D. Rotational
Explanation
The Navier-Stokes equation includes viscous shear-stress terms, so it is the governing equation for viscous fluid motion. For an ideal non-viscous flow, it reduces to the Euler equation.
