The velocity field of a flow is given by where x and y are
Chapter 4, Problem 4.7(choose chapter or problem)
The velocity field of a flow is given by \(\mathbf V=20y/(x^2+y^2)^{1/2}\mathbf{\hat i}-20x/(x^2+y^2)^{1/2}\mathbf{\hat j}~\mathrm{ft/s}\), where x and y are in feet. Determine the fluid speed at points along the x axis; along the y axis. What is the angle between the velocity vector and the x axis at points (x , y) = (5, 0), (5, 5), and (0, 5)?
