Given the system shown below, what is the pressure reading at Gage A?

Gage A Air Water CCI4 (s. g. 1.59) 24\" Hg Air 10 psi Water

Solution

Since the water level is same in left and right system, so the pressure at that point is same. Therefore irrespective of all the components and complications present, the pressure reading will be 10psi (same as right system)
