Thank you for this great video. As a student of hydronics, I hadn't appreciated that turbulent flow is beneficial in applications where the aim is to transfer heat between the water and the pipe walls.
I have a question about the return air plenum requirement: does the requirement described in the video only apply if a suspended ceiling is actually used as a return air plenum? If all the return air is ducted inside the suspended ceiling, does the requirement no longer apply?
First off ALWAYS refer to the local building department and building codes. That stated as a general rule the Building Code in Canada ( where we are based) if it is fully ducted these comments do not apply. It only applies when the return IS THE cavity in the air space.

Laminar flow is a problem. Glad you enjoyed the video Tony.
