6.11 For incompressible fluids the volumetric dilatation rate must be zero; that is, V. V = 0. For what combination of constants, a, b, c, and e can the velocity components u = ax + by v = cx + ey W = 0 be used to describe an incompressible flow field? 6.18 The velocity components of an incompressible, two- dimensional velocity field are given by the equations u = 2xy v = x² - y² Show that the flow is irrotational and satisfies conservation of mass. 6.11 For incompressible fluids the volumetric dilatation rate must be zero; that is, V.
