The basic hydrostatic equation can be simplified for manometers as follows
[tex]P_B - P_A= - \rho*g(z_B-z_A) [/tex]
I am having trouble figuring out what the order in which I should put the values of the pressure and elevations. Which is the higher elevation and which is the higher pressure? The order matters because the pressure can be below atmospheric. I can't seem to figure this out like I do with mechanics which pretty intuitive.
