Thanks for the reply. the fan draws (approximately) 30 000 cfm at full capacity according to the manufacturer. So since the head loss due to the pipe lengths and minor sources is minimal (I calculated it to be about 5% or so for the entire system) I can just assume the flow drawn through each...
I'm working in an engineering internship after my first year and we haven't covered fluid dynamics in my program yet. I've been assigned to find flow rates and velocities in several branches of a suction (dust collection) system in our factory. The main branch has a diameter of 30" and is...
