Dustline Clogging 1

[vulcan.]

Hi, I have trouble understanding clogging-pressure drops.
Dust build up causes clogging, but how will it affect the pressure drop across the clogged volume?

Your help will be very much appreciated.

Pipe fouling will simultaneously decrease the area available for flow while also increasing effect pipe surface roughness. Both will increase pressure drop.
