The two tubes in a differential bubbler system are placed in a liquid with $SG=2\mathrm{.}4$

If the bottom ends of the bubbler tubes are $3\mathrm{.}5$ and $42\mathrm{.}7$ in below the surface of the liquid, Find the differential pressure

supplied to the two bubblers.

Density of Water $=0\mathrm{.}036l\frac{b_m}{i}{n}^3$
