SG$=0\mathrm{.}876.$ The tank on the left is open to

atmosphere at the top. The density of the air is

$1\mathrm{.}2$ kg$/$ m$^3.$ The tank on the right is closed at the

top with air inside, as shown. For the dimensions

below, find the pressure in Pascal at points A and

B $($black dots$)$ and the pressure gauge reading at

the bottom right$-$ hand side of the tank $($kPa$)$ in
