Understanding Fluid Statics: Solving Gage Pressure Problems

[brk51]

Homework Statement

All over the place here so bare with me, I'll get the hang of it eventually.

-----For these types of problems.. can you start at either the top of the tank or from point a?
-----Given specific Gravity, you need gamma of the unknown fluid so you multiply it by the density of water and gravity correct?

Homework Equations

SG = gamma(fluid) / gamma(water) gamma = density * gravity
Delta P(P2 - P1) = -gamma(fluid) * Delta Y(Y2 - Y1) >>>>> = -[(gamma water * gravity) * SG]

Can you please clean this up by writing over neatly. It is very hard to read your handwriting, particularly this signs. It looks like you have the right idea conceptually, but, it's hard to tell.
