Generaly, I use about 50% for coaxial piston valves.
I don't know how accurate that is, and it's not exactly backed up by crono data... but 30% is way too low, and the HVPL-01 is giving me numbers in that vicinity. (samewhere between 55 and 80some%) |

| I was wondering this last night, when I put in a higher number it says that it's optimistic but is 100 an achievable if this is how much flow is there with out using a burst disk. |

| Squishy, I'm pretty sure that even a strait section of pipe has a flow coef. lower than 100%. |

As I said in the other topic, it's about 65% for straight pipe.
What 100% represents, I don't know. |
