Often data for valves states the air flow requirement and pressure drop
However, it is not too easy to say what the air flow will be with a specific
blower. This routine estimates the back pressure of the valve for any air flow
rate, so you can see from graphs of flow vs back pressure for the fan,
exactly where the fan and tube data cross, and so can determine the actual
flow rate.
