Filling Heat
If diving cylinders are filled too quickly, the gas inside them becomes hot as a result of adiabatic heating, increasing in pressure, which results in a drop in pressure when the cylinder cools later. Cylinders are often filled at a rate of less than 1 bar (100 kPa or 15 lbf/in²) per second to reduce this increase in temperature. In an attempt to cool the cylinder when filling, some people “wet fill”, immersing their cylinders in a cool water bath. This increases the risk of internal cylinder corrosion by moisture from damp components entering the cylinder during filling.

Famous quotes containing the words filling and/or heat:
“the gap of today filling itself
as emptiness is distributed
in the idea of what time it is
when that time is already past”
—John Ashbery (b. 1927)
“I have a faint cold fear thrills through my veins,
That almost freezes up the heat of life.”
