A pressurized vessel contains water with some air above it is shown in Figure 4.
A multi-fluid manometer system is used to determine the pressure at the airwater interface, point D. The specific gravity of oil and mercury is given to be 0.9
and 13.6 respectively. Given that h1, h2 and h3 are 0.24 m, 0.35 m and 0.52 m
respectively, determine:
(a) the gauge pressure at point B
(b) the absolute pressure at point D
