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
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.
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.
The pressure at standard temperature and pressure (STP) is 1 bar.
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
1 bar is equivalent to 100,000 pascals (Pa). This unit of pressure is commonly used in meteorology and various engineering applications. To put it in perspective, 1 bar is slightly less than atmospheric pressure at sea level, which is approximately 1.01325 bar.
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.
