## Question:

For each statement, choose whether the statement is true or false and discuss your answer briefly. For each statement it is assumed that the proper boundary conditions and fluid properties are known.

(a) A general incompressible flow problem with constant fluid properties has four unknowns.

(b) A general compressible flow problem has five unknowns.

(c) For an incompressible fluid mechanics problem, the continuity equation and Cauchy’s equation provide enough equations to match the number of unknowns.

(d) For an incompressible fluid mechanics problem involving a Newtonian fluid with constant properties, the continuity equation and the Navier–Stokes equation provide enough equations to match the number of unknowns.
