Units of Pressure

Units of Pressure

Units of Pressure

(OP)
I have encountered a unit of pressure labeled 'ata'.  I was inclined to think this was atmospheres absolute but the numbers do not seem to work out.  Any input would be appreciated.

RE: Units of Pressure

Atmospheres absolute, if I recall correctly

RE: Units of Pressure

1 ata = 1 kp/cm2 absolute pressure

1 bar = 1 N/m2 = 1.0197 kp/cm2

1 kp = 1kg-force

mayby this helps

Kind Regards,

RE: Units of Pressure


To hahor,

From your own correlations, since one standard atmosphere ≈ 1.01325 bar, it follows that 1 standard atmosphere ≠ 1 kgf/cm2

but is ≈ 1.033 kgf/cm2

kgf = 1 kg-force.

RE: Units of Pressure

For purity sake, avoid grams as a unit of force.  That's just wrong.

RE: Units of Pressure

to 25362

please do do confuse standard atmospheric pressussure

and [at] "Technische Atmosphäre"

1 at = 1 kp/cm2 per definition

There is another pressure unit [atm]  "Standardatmosphäre" which is equal to 101325 Pa

for further identification [at] can be extended as [ata] Technische Absolut Atmosphäre or [atü] Technische Überdruck Atmosphäre.

I know this might be confusing, but this is all due to history.

Kind Regards,
hahor

 

RE: Units of Pressure

To habor,

The technical atmosphere = 1 kgf/cm2 is not in frequent use. If not otherwise indicated, at present, 1 atmosphere is considered a standard atmosphere per the SI (International System of Units), equal to 1.013250*E+05 Pa.
