Question: Converging duct flow is modeled by the steady, two - dimensional velocity field vec ( V ) = ( u , v ) = (

Converging duct flow is modeled by the steady, two-dimensional velocity field vec(V)=(u,v)=(U0+bx)vec(i)-byvec(j). As vertical line segment AB moves
downstream it shrinks from length to length + as illustrated in the figure. Choose the correct analytical expression for the change in length of the line
segment, . Note that the change in length, , is negative.
