2. In class, we discussed several different flow scenarios for which we can make enough
assumptions to simplify the Navier-Stokes equations enough to solve them and obtain
an exact solution. Consulting the cylindrical form of the Navier-Stokes equations copied

a.) In class, we discussed how the Navier-Stokes equations are an embodiment of Newton's
2nd law, F = ma (where bolded terms are vectors). Name the 3 forces that we are considering in
our analysis of fluid flow for this class.

class. (For this problem, only the x direction equation is shown for simplicity). Note that
the equation provided is for a Cartesian coordinate system. In the spaces below, indicate
which of the following assumptions would allow you to eliminate a term from the
equation. If one of the assumptions provided would not allow you to eliminate a
particular term, write "none" in the space provided.
