Yes as the short radius fittings offer greater friction losses
to reduce the pressure on punches and turret.
since there is less gravity when you go higher in the atmosphere, there is less air being pulled down and causes the reduce of air pressure.
Gravity - or, more precisely lack of it ! The further away from the centre of the earth you are - the less gravity affects apply. Standard air pressure at sea-level is approximately 14 PSI - but that reduces exponentially with altitude.
Using compression.
Compression socks are great because they reduce muscle damage. They reduce muscle damage by increasing the circulation in the legs and feet by compressing them.

Inorder to reduce the overall machine load, while I observed in my machine I could see only one set of punches coming under a pressure roll & other pressure roll is free at that time. So load on pressure rolls moreover overall machine load is reduced to half during compression. Sumit Ch. Shrestha
Dynamic compression is also known as dynamic range compression. This compression is used mostly in DVDs and car CD and is used to compress or reduce the loud sounds on music tracks.
File compression uses software algorithms to reduce file size by reducing the bit-rate of a file. Lossy compression takes it a bit further and lowers the quality of thr file to make it even smaller. Lossy compression is commonly used for media files, but would not be appropriate for other types of files.

A pressure gauge simply measures and visibly indicates pressure in a system . It does not reduce the pressure. For that you need a PRV (pressure reduction valve ).
