Cut away of a gas compressor. The red impellers have one side removed to show the divergent profile that helps compress the gas

  • @TubeCritter111 "No physical volume reduction occurs within a centrifugal compressor"

    .

    I'm sorry, but that statement is false. There is a tremendous amount of volume reduction in multi-stage compressors. That is why it couldn't work as a pump, or at least it's efficiency would be drastically reduced if it was used as a pump, as there would be a "fluid dynamic mismatch" between the large front and small rear stages. Pumps are meant for incompressible fluids, and have exactly identical stages.

  • @BetyarPali I have been researching the correlations between what the industry calls pumps and what it calls compressors for the last five years, and found that, at least in the centrifugal case, there is no discernible difference. No physical volume reduction occurs within a centrifugal compressor, which is why it is called a dynamic compressor. This is also why indeed it can pump an incompressible liquid. The same is true with rotary and lobe compressors.

  • @TubeCritter111 This is a gas compressor, it's not a water pump, although the two look a lot alike. It wouldn't work as a water pump because water is completely incompressible, while natural gas is very compressible. But you're right, it can probably handle an enormous volume flow of gas in 10 seconds, probably many cubic feet of gas per minute.

  • Cool video! I studied about this in my book. But now I see it, it makes me appreciate it more! Thanks.

  • I wonder how well that would work as a boiler feedwater or reverse osmosis injection pump. I'm willing to bet it could probably empty a large swimming pool full of water in about 10 seconds at full speed.

  • Anybody got a light?

  • r u guys in the background choking off the gas or wot
