**Simple Fluid Mechanics-differential manometer question. Please :)**

Can someone please help me on this differential manometer question??

Let me retype the question because my handwriting is sloppy. "The manometer fluid in the manometer has specific gravity of 3.46. Pipes A and B both have water. If pressure in A is decreased by 1.3psi and pressure in B increases by 0.9psi, determine the differential.

Gamma(water) = 62.4 lb/ft^3

SG*Gamma(water)=Gamma(gage fluid)=(3.46)*(62.4lb/ft^3)=215.904lb/ft^3

I scanned what I did. I tried a few other methods but they were borderline retarded and didnt make sense so I didnt bother attaching them.

Please help!

Oh the answer is 4.06ft. The best I can muster is 4.5641ft.
