P=rho*g*h
P= pressure
rho= density = 1000 kg/m^3 at about 20C
g= gravitational constant on earth at sea level = 9.81 m/s^2
h= height
P=1 bar=1x10^5 Pascals = 1x10^5 N/m^2 (based on the definition of the Pascal unit)
since by definition 1 Newton= 1 kg*m/s^2
1x10^5 N/m^2= 1x10^5 kg*m^2/(m^3*s)= 1x10^5 kg/(m^2*s)
1x10^5 kg/(m^2*s) = 1000 kg/m^3 *9.81m/s^2 * h
solving for h yields:
h= 1x10^5/(1000*9.81)= 10.19367 meters
This value might vary slightly due to the affect of temperature on the density of water.
Depends on the altitude. But its meters of head times 0.09804 for calculating bar. Thus 1 meter of head, times 0.09804 tells us a meter of head is 0.09804 bar of pressure
1 BAR = 10 Meters
Pounds per Square Inch or Psi is a unit of pressure or stress. 1 bar is equal to 14.50377 Psi.
1 bar = 14.5 PSI
1 bar is 14.5038 psi. Scroll down to related links and look at "Conversion of pressure or stress units".
If an instrument is indicating a wrong parameter instead of actual. Say the actual pressure is 1 bar but the instrument is reading 1.5 bar is an example of instrumental error.
The micron is 1 x 10-6 meters, so 5 microns is 5 x 10-6 meters. This is also 0.005 millimeters, or 0.000197 inches.
90 meters. Every 10 meters, the pressure increases by approximately 1 bar, to this, you have to add the atmospheric pressure, which is also approximate 1 bar.

1 Pa = 1 N/m2 = 10−5 bar = 10.197×10−6 at = 9.8692×10−6 atm,
The recommended water pressure is 0.5 to 1 bar
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).
12.6 meters 0.1 bar is gained for every meter.
10.332 metres.
1 1 Meter of water column 9800 pascals = 10 Kpa = .1 Kg/cm2 UNIT FOR USAGE 10 METER OF WATER COLUMN 1 kg/cm2 I hope this answers your question. If you need any clarification please get back to me at mrajkumar0865@rediff.com
Air pressure (at sea level) is about 1 bar; every 10 meters below the water surface, pressure increases by about 1 bar - that gives a total of 1 + 0.4 = 1.4 bar. (1 bar is about 1 atmosphere.)
Those units measure very different things; you can't compare them.
Pressure at a given depth of water can be calculated using a formula like, "#1 #1kgf/cm2." Therefore, water pressure at 2000 meters below sea level will be around 1.2 bar.
