HW4 Q3.5 Setting up dP/dx
I managed to set up \eta \nabla^2 v_\mathrm{f} = \frac{\partial p}{\partial x} + c \frac{\partial U}{\partial x} = \frac{\Delta p - \Delta \Pi_\mathrm{eff}}{L} = \frac{\Delta P}{L} but now I am stuck because I don't know how I should set up dP/dx. Could you give me a hint?
