Bar is a unit of pressure. 20 bar is approximately 20 times the atmospheric pressure.
Air pressure is measured in bar.
A barometric pressure of zero is a vacuum.
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).
1 Bar is 1 atmosphere of pressure. Much used in very high pressure work. 1 Bar is approx 1kg/cm2
I cannot answer this question.
Bar is a unit of pressure. 20 bar is approximately 20 times the atmospheric pressure.
Bar is a unit used to measure pressure, one bar is the normal atmospheric pressure of the on the surface of the earth, and ten bar is when the pressure is ten times the normal atmospheric pressure on the surface of the earth.
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.
Resion is not an English word.
16.2 bar = 1,620 kPa
Air pressure is measured in bar.
bar is unit of pressure
10 m depth is 2 bar pressure.
The boilers which produces steam of pressure 80 bar or more than 80 bar are called high pressure boilers.

PN 16 valve can withstand 5 bar pressure. I have experienced that at 7 bar it cannot hold the pressure and starts to leak.
