Question: A velocity field is given by vec ( V ) = 3 x ( 2 + c o s ( t ) ) h a

A velocity field is given by vec(V)=3x(2+cos(t))hat(i)-3y(2+cos(t))hat(J)
(i) What are the dimensionality and directionality of the flow field?
(ii) Derive the equation of streamline at time t=0, passing through (2,4). Does the streamline vary with time?
(iii) Is this an irrotational flow? Justify your answer.
