Re: Parallel or Series, which is better?

Regardless of whether you put one valve or 10 valves downstream, the rate at which air will go through that one tube and one regulator is not dependant on whether the tanks are in series or parallel. The storage volume will discharge at the same rate.
My answer is correct.

No valve in the KOP will flow gas faster than the tubes supplied, thus the tubes are not the controlling restrictor.

No valve will flow anywhere near the flow capacity of the regulator, thus again, the controlling restrictor is the valve.

Putting tanks in parallel will do nothing if the controlling restrictor is not the flow orifice from the tanks.

My explaination was to show how he could get higher flow and to point him in the proper direction as to why the flow through his pneumatic system is what it is.

His question was trying to flow gas faster, thus my suggestion to parallel the controlling restrictor, not the tanks or the regulators.

It's not splitting hairs ... it's the physics of gasses and I'm trying to get him to understand the answer, not give the answer to him.
