ah. we used to use some rules of thumb in development of fire suppression systems. if it was single phase flow, i.e. CO2, we'd use 1X the pipe diameter following an elbow or tee prior to pacement of another elbow or tee.
with dual phase compressible flow (i.e. FM-200 w/ Nitrogen), we had to be more careful; the tees & elbows would cause collapse to the liquid phase & we'd have to give it 2X to 3X the tube diameter prior to tees, otherwise all the gas would go one way & all the liquid would go another.
with the intake stuff here, we're using much lower velocities & i would think it would matter a lot less. what do you think is reasonable? 1X the tube diameter?
