I have a set up that inflates a rubber jacket in order release the metallic rings from underneath it. I am currently having issues with not having enough pressure (force) at the outlet to inflate the rubber jacket. I want to reduce the size of the pipe in order to increase the velocity, will this work?
Assuming somewhat approximately the gas is in-compressible, then (continuum equation):
where the $A$ are the cross-sections of the pipe.
So we can write:
Using diameters $D$:
So fitting an adaptor with $D_2<D_1$ will increase $v_2$.
