Some velocity measurements in a three-dimensional incompressible flow field indicate that u = 6xy2 and v = —4y2z. There is some conflicting data for the velocity component in the z direction. One set of data indicates that w = 4yz2 and the other set indicates that w = 4yz2 — 6y2z. Which set do you think is correct? Explain.
