Prob. $2\mathrm{.}6\mathrm{.}17$ p$.$ IP$-15[$Ans: $26\mathrm{.}9$kPa;$0\mathrm{.}202m].$

$2\mathrm{.}6\mathrm{.}17$ WP SS The cylindrical tank with hemispherical ends shown in Fig. P$2\mathrm{.}6\mathrm{.}17$ contains a volatile liquid and its vapor. The liquid density is $800k\frac{g}{m^3},$ and its vapor density is negligible. The pressure in the vapor is $120$kPa $($abs$),$ and the atmospheric pressure is $101$kPa $($abs$).$ Determine: $($a$)$ the gage pressure reading on the pressure gage, and $($b$)$ the height, $h,$ of the mercury in the manometer.
