Kinematics 07 Rotational Irrotational Flow

Irrotational flow may be described as flow in which each element of the moving fluid suffers no net rotation from one instant to the next with respect to a given frame of reference. In flow along a curved path fluid elements will deform. If the axes of the element rotate equally towards or away from each other, then the flow will be irrotational. Vorticity is defined as circulation per unit area, Derivation for angular velocity vector, curl, vorticity and circulation
