A velocity field is specified as \(\vec{V}=a x y \hat{i}+b y^{2} \hat{j}\), where \(a=\) \(2 \mathrm{~m}^{-1} \mathrm{~s}^{-1}, b=-6 \mathrm{~m}^{-1} \mathrm{~s}^{-1}\), and the coordinates are measured in meters. Is the flow field one-, two-, or three-dimensional? Why? Calculate the velocity components at the point \((2,1 / 2)\). Develop an equation for the streamline passing through this point. Plot several streamlines in the first quadrant including the one that passes through the point \((2,1 / 2)\).
