volume flow rate through series of pipes

[Rehan Ali]

The drawing is of raw mill (cement factory). I would like to calculate total volume flow rate through main pipe and through branched pipelines. Fan is impeller type and capacity of fan is 200 m^3/min and RPM 1450. The fan is connected through a pipe which is connected with a bag filter.


Thanks

Well you need to find the fan curve and then work out your system curve.

See

http://curta.dlinkddns.com/html_tutoring/PE/HVAC_Equipment_Systems/fancurve.htm

for some simple examples

Where the two intersect will be your volumetric flowrate.

With a filter, your system curve needs to look at when the filter is clean and when it is dirty.

You will need to establish a means to measure the differential pressure across your filter to know when to change it.

"Capacity" of a fan is relatively meaningless with knowing what the differential pressure is across the fan and how much resistance there is to flow.

My guess is that the flow could be anywhere from 20 m3/min to 300 m3/min.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

That is good suggestion. I try to work on your suggestion provided and than come back for further clarification.
