Air pressure variation with height

Hi,

I understand the thumb rule that " the pressure exerted by ten metres depth of water is approximately equal to one atmosphere". Is it applicable for pneumatic systems too ?? that with 10 m head difference in air pressure lines there would be 1 bar difference in pressure between the ends

Please advise

10m of water weighs the same as all the air above your head - so 10m of air is unlikely to weigh the same.
If the atmosphere is roughly 10,000m high then 10m head is about 10/10,000 of a bar different - otherwise you would need to decompress when standing up.
