Unformatted text preview: What is the angular velocity? If a small cross is placed at x=0,y=1 (with the two arms of the cross aligned with the x & y axes at first), draw how that cross would move. 4) Find the circulation about a circle of radius r centered on x=y=0 for the flow in 1) 5) Find the streamfunction for the flow in 1) 6) Is there a velocity potential for the flow in 1)? Explain your answer. 7) A generalization of the flow in prob 1 is u= a x + b y ; v=c x + d y Where a,b,c,d are constants. What values of a,b,c,d would allow there to be a velocity potential? What values of a,b,c,d would allow there to be a stream function? What values of a,b,c,d would allow both a streamfunction and a velocity potential?...
