Four static microfluidic tracks are open to atmospheric pressure \(P_0\) at their top surfaces and contain stationary incompressible fluids, as shown in the diagram. Track 1 contains a fluid of density \(2\rho\). Track 2 contains two immiscible fluid layers of densities \(\rho\) and \(3\rho\). Track 3 contains a fluid of density \(\rho\) in a channel with a slanted section angled at \(30^\circ\) to the horizontal. Track 4 contains a fluid of density \(2\rho\) in a channel featuring a wide upper reservoir of cross-sectional area \(3A\) connected to a narrow lower neck of area \(A\). Which of the following correctly ranks the total hydrostatic pressures \(P_W, P_X, P_Y,\) and \(P_Z\) at the marked nodes?
