Piping size

0.4 Mach is the point at which air becomes turbulent and losses in efficiency start to occur exponentially. The key is to stay under that speed. You want to use the smallest piping possible that still flows enough to meet your needs. Larger than necessary piping increases lag time with no measurable gain.

Values are corrected to air temperature 40 deg C, humidity 60%, pressure 100 kPa
