The velocity field for a plane source at a distance \(h\) above an infinite wall aligned along the \(x\) axis was given in Problem 6.6. Using the data from that problem, plot the pressure distribution along the wall from \(x=-10 h\) to \(x=+10 h\) (assume the pressure at infinity is atmospheric). Find the net force on the wall if the pressure on the lower surface is atmospheric. Does the force tend to pull the wall towards the source, or push it away?
