Fluid Kinematics - Incompressible and Irrotational Flow - GATE ME '09

You are asked to evaluate assorted fluid flows for their suitability in a given laboratory application. The following three flow choices. Expressed in terms of the two - dimensional velocity fields in the x− y plane, are made available. P: u=2y,v=−3x Q: u=3xy, v=0 R: u=−2x, v=2y

Which flows should be recommended when the application requires the flow to be incompressible and irrotational? A. P and R B. R only C. Q and R D. R only
