Atmospheric pressure is approximately equal to 14.7 pounds per square inch
One bar is equal to one atmosphere
None! A tank at atmospheric pressure already has an absolute pressure of 1.013 bar.
1 Bar is 1 atmosphere of pressure. Much used in very high pressure work. 1 Bar is approx 1kg/cm2
10.20 meters in depth
The pressure at standard temperature and pressure (STP) is 1 bar.
1 barg stands for 1 bar gauge pressure, which is the pressure measured above atmospheric pressure. It indicates a pressure of 1 bar higher than ambient atmospheric pressure.
A bar is a unit of pressure, not a unit of weight, nor of mass. A bar is 100,000 pascal, or 100,000 newton / meter2.
A Liter is a measure of volume; a bar is a measure of pressure - your question is like asking how much does a foot weigh.
Please note that bar is the unit of pressure and kN is the unit of Force. Direct conversion from bar to kN is not possible. 1 bar = 100 kN/m^2 or kilopascal
Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.
If you mean in the ocean, approximately every 10 meters pressure increases by 1 bar. Assuming you want absolute pressure, at the surface you already have a pressure of approximately 1 bar - the atmospheric pressure. You can base your calculations on that.
Water pressure increases by approximately 1 bar for every 10 meters of depth in freshwater. At a depth of 10 meters, the water pressure would be about 1 bar, in addition to the atmospheric pressure at the surface, which is roughly 1 bar as well. Therefore, the total pressure at 10 meters depth would be about 2 bars.
1 bar = 14.7 psi therefore 9 bar = 132.3 psi
