A vacuum gage indicates that the pressure of air in a closed chamber is $0.2$ bar (vacuum). The pressure of the surrounding atmosphere is equivalent to a $750-\mathrm{mm}$ column of mercury. The density of mercury is $13.59 \mathrm{~g} / \mathrm{cm}^{3}$, and the acceleration of gravity is $9.81 \mathrm{~m} / \mathrm{s}^{2}$. Determine the absolute pressure within the chamber, in bar.

00:01 All right, so let's say we have a room filled with air and we're told that the vacuum pressure inside the room is 0 .2 bars.
00:11 So it's a vacuum pressure, so we'll say it's negative.
00:14 And of course the atmospheric pressure elsewhere is just one bar, which we can say is about 750 millimeters of mercury approximately.
00:30 And so we want to find the gauge pressure, or sorry, the absolute pressure inside the chamber...
