In the following equations, u and v are the velocities in the x- and y- directions, respectively and t is time. The flow field that CANNOT be termed as incompressible is
- A. , 3 2 3 2 u = x + x y v = y + y x
- B. 10 , 10 u = xt v = yt −
- C. ( ) ( ) 1/7 / , 0 constant u = y v = δ δ=
- D. 2 , 2 u = y v = x
Answer: A. , 3 2 3 2 u = x + x y v = y + y x
