This is for fluids and I'm completely lost. Can someone help me with this?

1. (5 pts) Consider steady, incompressible, two-dimensional flow through a converging duct. An approximate velocity field for this flow is: V=(u0+bx)i^byj^ where U0 is the horizontal speed at x=0. (This velocity field is fairly accurate through most of the flow, but ignores viscous effects and so will be inaccurate very close to the walls). Gravity can be considered negligible. Find pressure as a function of x and y
