An idealized velocity field is given by the formula
V = 4txi 2t 2 yj + 4 xzk
Is this flow field steady or unsteady? Is it two- or three-dimensional? At the point (x, y, z) =
(1, +1, 0), compute (a)

Water flows steadily through the
round pipe in the figure. The entrance

Uo/umax for this incompressible flow.
Solution: Inlet and outlet flow must balanc
