A two-dimensional flow field is given by u=2+xy+3t^2, v=2xy^2+t. Find the velocity and acceleration of a particle of fluid at point (2,3) at t=4. Specify units in terms of L and T.
Consider the pressure-driven flow between stationary parallel plates separated by distance 2b. Coordinate y is measured from the channel centerline. The velocity field is given by u=u max(1-(y/b)^2).
