Two-dimensional irrotational fluid flow is conveniently described by a complex poten- tial f(z) = u(x, v) + iv(x, y). We label the real part, u(x, y), the velocity potential, and the imaginary part, v(x, y), the stream function. The fluid velocity V is given by V = Vu. If f(z) is analytic: 11.2.11 (a) Show that df/dz= Vx - iVy. (b) Show that V. V=0 (no sources or sinks). (c) Show that V x V=0 (irrotational, nonturbulent flow).

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
