In scuba diving, bar is also the most widely used unit to express pressure, e.g. 200 bar being a full standard scuba tank, and depth increments of 10 metre of seawater being equivalent to 1 bar of pressure. Many engineers worldwide use the bar as a unit of pressure because, in much of their work, using pascals would involve using very large ...
Introduced in 1872, 68-pounders adapted in this way had a calibre of 6.29 inches (16.0 cm) and were known as a RML 68-pounder, or officially as the RML 80-pounder 5 ton. [28] With a 10 lb (4.5 kg) powder charge they could fire an 80 lb (36 kg) projectile at a muzzle velocity of 1,240 feet per second (380 m/s). [29]
The outside water pressure increases with depth and so the stresses on the hull also increase with depth. Each 10 metres (33 ft) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 ft), the hull is withstanding thirty standard atmospheres (30 bar; 440 psi; 3,000 kPa) of water pressure.
Her owner humorously notes in the comments section that Emmy Lou has a particular fondness for boxes and bags, “so she tries to fit into every single one regardless of size.”
The unit used in the US is the foot sea water (fsw), based on standard gravity and a sea-water density of 64 lb/ft 3. According to the US Navy Diving Manual, one fsw equals 0.30643 msw, 0.030 643 bar , or 0.444 44 psi , [ 1 ] [ 2 ] though elsewhere it states that 33 fsw is 14.7 psi (one atmosphere), which gives one fsw equal to about 0.445 psi.
For example, in the US and in many diving resorts in other countries, one might find aluminum cylinders of US manufacture with an internal capacity of 0.39 cubic feet (11 L) filled to a working pressure of 3,000 psi (210 bar); Taking atmospheric pressure as 14.7 psi, this gives 0.39 × 3000 / 14.7 = 80 ft 3 These cylinders are described as "80 ...
