About 160 psi or 11 atm
In water, every 10 meters you go down, the pressure increases by 1 bar, approximately. To this you must add the air pressure, which is also approximately 1 bar (depending on whether you want gauge pressure or absolute pressure).
To experience a pressure of 2 ATM, you would need to dive to a depth of 20 meters (2 ATM = 1 ATM (surface) + 1 ATM (pressure at 10 meters depth)). At a depth of 100 meters, the pressure would be approximately 11 ATM (1 ATM at surface + 1 ATM for every 10 meters).
Per the ICAO (International Civil Aeronautics Organization) standard atmosphere, the pressure at 1000 ft is 0.9644 times sea level, which is 1013.25 mb. So at 1000 ft, the "standard" pressure is 977.18 mb.
The pressure at a depth of 100 m below the surface can be calculated using the formula: pressure = density x gravitational acceleration x depth. Given the density of 1150 kg/m^3 and assuming a gravitational acceleration of 9.81 m/s^2, the pressure at 100 m below the surface would be approximately 1147,850 Pa.
Water boils at 100 degrees Celsius under normal atmospheric pressure.
In water, every 10 meters you go down, the pressure increases by 1 bar, approximately. To this you must add the air pressure, which is also approximately 1 bar (depending on whether you want gauge pressure or absolute pressure).
The water pressure depends only on the depth, not on the size or shape of the vessel. The pressure increases at about 1 atmosphere (or bar) every 10 meters.
Pressure and depth are related in that pressure is proportional to depth. The equation to find pressure at a certain depth is p=dgh, where p is the pressure, d is the density, g is the acceleration of gravity and h is the depth.
The volume of gas at a depth of 100 feet would depend on the pressure and temperature at that depth. As pressure increases with depth, gas volume decreases. To calculate the exact volume, you would need to know the specific pressure and temperature conditions at that depth.
At 100 psi gauge pressure, the boiling point of water is approximately 324.7°F (162.6°C). This is higher than the standard atmospheric pressure boiling point of 212°F (100°C) due to the increased pressure causing the water to boil at a higher temperature.
The boiling point of water at 6 barg (bar gauge pressure) is approximately 152.9°C. At this pressure, water requires a higher temperature to boil compared to its boiling point at standard atmospheric pressure (100°C).
1 Bar represents one atmosphere of air pressure. 10 Bar is approximately equal to 100 Meters of water depth. 1 meter = 3.28083989501 feet. It follows that 100 meters = 328.083989501 feet. Therefore, 10 Bar is approximately equal to the expected pressure at 328.083989501 feet of water depth (not sea level).
To experience a pressure of 2 ATM, you would need to dive to a depth of 20 meters (2 ATM = 1 ATM (surface) + 1 ATM (pressure at 10 meters depth)). At a depth of 100 meters, the pressure would be approximately 11 ATM (1 ATM at surface + 1 ATM for every 10 meters).
High oil pressure or a faulty oil pressure gauge.
Pressure in seawater at 100 feet is 44 psi. Or, .44 pounds per square inch per 1 foot. For Fresh water, it is .43 psi per foot.
mmWG is a pressure unit. its something like mm Hg, however in mmWG, W refers to water and G refers to gauge pressure. Hence, mm WG refers to the gauge pressure in terms of milimeters of water.
Per the ICAO (International Civil Aeronautics Organization) standard atmosphere, the pressure at 1000 ft is 0.9644 times sea level, which is 1013.25 mb. So at 1000 ft, the "standard" pressure is 977.18 mb.
