Fundamentals of Fluid Mechanics
$\mathrm{fcot}^{2}$ The velocity field of a flow is given by
\[
\mathbf{V}=(3 y+2) \hat{\mathbf{i}}+(x-8) \hat{\mathbf{j}}+5 z \hat{\mathbf{k}} \mathrm{ft} / \mathrm{s}, \text { where } x, y, \text { and } z \text { are in }

feet. Determine the fluid speed at the origin $(x=y=z=0)$ and on the $y$ axis $(x=z=0)$
