Homework Statement
Two tanks, one containing SAE Grade 30 oil (density of 890 kg/m3) and the other containing carbon tetrachloride (density of 1,590 kg/m3) , are connected through a differential manometer as shown in the figure. Calculate the pressure difference between chambers A and B.

Homework Equations
760mm Hg = 760Torr. 760Torr = 1atm = 101300Pa.
P= Po + pgh
The Attempt at a Solution
The pressures are the same if there would have been no height difference.
Thus PA=890*1.1*9.8
and PB=1590*0.8*9.8
PB-Pa=2871.4 Pa.
This correct?
Quick question. why can't I use 0.3*300Torr to solve for pressure difference?
