Question:
Can you inject compressed air in a plastic pipe already filled with water. How can air even enter. I am told they are able to do it.


Replies:
The pipe has to stretch, the water has to compress, the air has to dissolve in the water, or some combination of the three.

Of course they can since air (a gas) is compressible. It would act like carbonation in seltzer water. Just get a plastic bottle of seltzer and feel how hard it is, then upon opening it goes soft, it is just the air coming out or in that case CO2.

Michael Baldwin

If there is no "air space" left in the pipe, the answer is no except for the small amount of air that will dissolve in the water.
