Knowledge review 1 - ANSWER- At 10 metres/33 feet you're _____ bar/ata of total pressure and the air density is ___ times as great as at the surface. a. 1 b. 2 c. 3 d. 4 - ANSWER-b. 2 *Pressure increases by one bar/ata for every 10 metres/33 feet of depth. So, at 10 metres/33 feet, the total pressure is 2 bar/ata (one from water pressure and one from atmospheric pressure). Density increases proportionally, so at 2 bar/ata the density is 2 times as great, at 3 bar/ata the density is ...
