Refrigerant Piping Velocities

[Mntwin]

Does anyone have anything that would indicate the proper min and max velocities through the suction and liquid lines of a commercial A/C system? I've gotten completely different results as I dig into this. Trane will say one thing, McQuay says something else, and others don't agree with either of them.

Do you have something for R410A refrigerant that might list min and max velocities through horizonatel and vertical pipe?

I would apprecite it if you had something to share.

Thanks.
