Consider the flow field with the velocity given by \(\vec{V}=4 y \hat{i}+3 x \hat{j}\), where the velocity is in \(\mathrm{ft} / \mathrm{s}\) and the coordinates are in feet. The fluid density is \(1.5 \mathrm{slug} / \mathrm{ft}^{3}\) and gravity acts in the negative \(y\) direction. Determine general expressions for the acceleration and pressure gradient. Plot the acceleration and pressure gradient in the \(y\) direction for \(x=0\) and \(x=2 \mathrm{ft}\).
