Remember: it is estimated that drainage and sewage systems - as designed by civil engineers - have saved more lives than all of medical science. **Fluid** **mechanics** is integral to our work. These types of flow are subject to the boundary-layer approximation. The resulting **momentum** **equation** remains nonlinear, since the influence of inertia on the **fluid** motion remains in the balance.
