If velocity vector is given for a flow by V= (u, v) = (ax + b)i + (-ay + c)j. Decide that is it irrotational

If velocity vector is given for a flow by V= (u, v) = (ax + b)i + (-ay + c)j. Decide that is it irrotational flow or not? If it is irrotational, generate an expression for the velocity potential function. It is noted that the flow is steady, 2D and incompressible. If you want to make a novel design for a motorcycle rider helmet, make a list to describe the three necessary conditions for complete similarity between a model and a prototype. And explain them.
