Volume Damper Design
first, i have spent some time trying to figure out which forum to post my question at, and i hope this is correct. Please remove it in case i was wrong. i hate breaking the rules
Well, i'm working on a project of manufacturing an in-house volume control dampers, i'm working on the design now and it's almost done.
However, i'm still stuck at some points without any answers:
1- how to decide proper number of blades ? (in case of having diffrent widths, e.g.: either 5 blades of 4" or 4 blades of 5")
2- how to decide where to place the extended shaft or the manual handle, top balde or center or bottom ? based on what.
Thanx in advanced guys.
