Based on your calculations with 150mm ducting and a duct velocity of 29.3 m/s, using Hemjo’s table it looks to me like that velocity will accommodate all or most activities in my wood workshop - in many cases with reasonable head room. Or am I missing something in that simple interpretation eg losses due to various factors?
