Continuous decompression to 1.9 bar over 15 minutes; 60 minutes at 1.9 bar (30 fsw) Continuous decompression to surface over 15 minutes; Neurological decompression sickness, arterial gas embolism or unresolved symptoms after 10 minutes at treatment pressure: [18] 30 minutes at 2.8 bar (60 fsw) Continuous decompression to 1.9 bar over 30 minutes
A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...
Pressure of an average human bite [citation needed] 2.8–8.3 MPa 400–1,200 psi Pressure of carbon dioxide propellant in a paintball gun [64] 5 MPa 700 psi Water pressure of the output of a coin-operated car wash spray nozzle [58] 5 MPa 700 psi Military submarine max. rated pressure (est.) of Seawolf-class nuclear submarine, at depth of 500 m ...
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.
60 m (200 ft) Depth limit for a group of 2 to 3 French Level 3 recreational divers, breathing air. [17] 66 m (217 ft) Depth at which breathing compressed air exposes the diver to an oxygen partial pressure of 1.6 bar (23 psi). Greater depth is considered to expose the diver to an unacceptable risk of oxygen toxicity. [nb 2] 100 m (330 ft)
People over 60 face health concerns dramatically different than when they were younger. These important health issues need to be on all seniors' radar.
The pressure of seawater at a depth of 33 feet equals one atmosphere. The absolute pressure at 33 feet depth in sea water is the sum of atmospheric and hydrostatic pressure for that depth, and is 66 fsw, or two atmospheres absolute. For every additional 33 feet of depth, another atmosphere of pressure accumulates. [6]
In fact, he made her do it again -- and he called her new 144 over 92 reading "much better." ... "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
