The cylindrical tank with hemispherical ends shown in Fig. P2.46 contains a volatile liquid and its vapor. The liquid density is 800 kg/m3,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, manometer.
