Unless you’re really accustomed to ducts as well as their elements, resolving for the friction loss level is going to be difficult. Go ahead and let the gurus deal with Those people calculations.

I'm not member of CIBSE and in some cases get their CPD and various PDfs. They don't seem to be cheap. Is there any way to discover Those people tables and charts any place? nevertheless, I'm previously grateful to the work you might have carried out below.
