When designing a pneumatic system, the flow requirements and the system’s ability to transfer that flow, is imperative. Pipe size and frictional losses within the system are the critical factors that limit flow.
Probably the easiest way to visualize this is to put it in terms of electricity. The longer the cord, the more resistance and consequently capable of less amperage. The more amperage required the larger gauge wire is required. The same applies to air flow. The longer the pipe the more the resistance and the less flow of air it is capable of. The greater the volume of airflow demand the larger a pipe is required.
