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.

Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.

but i think the absolute pressure is P(pressure)/{p(density)*g(gravity)}

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.

Gauge pressure is what you get when you take the reading from your tire pressure gauge. Absolute pressure is the pressure inside your tires plus the atmospheric pressure, which is roughly; 14.7 psi, 101.3 kPa (kilo-Pascals), or one atmosphere. Absolute pressure measures all of the pressure on your tires, inside and out, whereas gauge simply measures the pressure inside the tire.

None! A tank at atmospheric pressure already has an absolute pressure of 1.013 bar.

The 'g' added on to bar means 'gauge', as opposed to bara, meaning 'absolute'. The 'zero' of a normal gauge is normally set at atmospheric pressure (things like tire pressure gauges, water gauges etc.) These gauges will read as "10 bar" but really mean that the absolute pressure is 10 bar + atmospheric pressure (~1.01325 bar). Some gauges however are absolute gauges. These might include weather gauges, or gauges on closed processes. bara = barg + atmospheric pressure

A pressure measurement, in comparison to atmospheric pressure on Earth, at sea level, near sea level, at standard temperature, usually expressing an absolute pressure (but does not have to be). 1 atmosphere absolute = 1.01325 bar absolute 1 atmosphere absolute = 101,325 pascal absolute 1 atmosphere absolute = 14.69595 psi absolute

53 feet = 16.154 4 meterthe water pressure at 16.154 4 meters = 1.61544 bars + 1 bar of atmospheric pressure makes the absolute pressure = 2.62 bars.

To convert bar to psia (pounds per square inch absolute), you need to add the atmospheric pressure in psia to the pressure in bar. 1 bar is approximately equal to 14.5038 psia (standard atmospheric pressure at sea level).

Yes, absolute pressure is the pressure measured with respect to a vacuum, while static pressure is the pressure exerted by a fluid due to its motion or position. While they are related, they are not the same as static pressure does not take into account the atmospheric pressure.

At the Bar was created on 2007-02-02.

To convert from barG (gauge pressure) to barA (absolute pressure), you simply add atmospheric pressure to the gauge pressure. Assuming standard atmospheric pressure is around 1 bar, the conversion would be -0.02 barG + 1 bar = 0.98 barA.

To convert kilopascals (kPa) to bar gauge (barg), subtract the atmospheric pressure (typically around 101.3 kPa) from the given pressure. In this case, 345 kPa - 101.3 kPa = 243.7 kPa absolute. Then, convert the absolute pressure to barg by dividing by 100, as 1 bar = 100 kPa. Therefore, 243.7 kPa / 100 = 2.437 barg.

The Abbreviation for Manifold Absolute pressure is MAP.

Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
