Problem $2$: Consider the two pipes, A and B $.$ What is the difference between the pressure at the center of pipe A

and the pressure at the center of pipe $B(p_A-p_B)?$ The fluids $1,2,$ and $3$ are kerosene $),$ water $(S=1\mathrm{.}0),$

kerosene $(S=0\mathrm{.}8),$ respectively $($ S is the specific gravity$).$ The temperature is $20$ deg C such that the density of the

water is $998k\frac{g}{m}.$ Let $x=0\mathrm{.}2m,y=0\mathrm{.}15m,z=0\mathrm{.}10m.$
