How should the air consumption for the instrumentation of pneumatic valves be calculated correctly? ? How is the air volume calculated based on the size of the cylinder? And how do you determine the size of the gas supply pipeline?
HG-T 20510-2014 Design Code for Instrument Air Supply
It seems that the figure above is only an estimate based on gas consumption; is there a precise calculation?
No, because the air consumption of control valves varies among different manufacturers and models, so it can only be estimated

It’s difficult to calculate the actual frequency of opening and closing for each valve, but there is generally a pattern regarding the total amount of gas used by many valves.
The air consumption of the control valve changes constantly, and it can only be estimated.
