$2\mathrm{.}3960$ A closed cylindrical tank filled with water has a hemispherical dome and is connected to an inverted piping system as shown in Fig. P$2\mathrm{.}39.$ The liquid in the top part of the piping system has a specific gravity of $0\mathrm{.}8,$ and the remaining parts of the system are filled with water. If the pressure gage reading at $A$ is $60$kPa, determine $($a$)$ the pressure in pipe $B,$ and $($b$)$ the pressure head, in millimeters of mercury, at the top of the dome $($point $C).$ Density water $1000$kg$/$m$3$
