What component of the NavierStokes Equation is the one that

What component of the Navier-Stokes Equation is the one that makes most problems difficult or impossible to solve analytically without major assumptions?

A. All three above

B. Local acceleration

C. Convection

D. Diffusion

Solution

Option A is correct. All the 3 components of the equaitons are require assumptions otherwise it can not be solved analytically.
