I would like to know the effect that pipe length has on flow rate for a fan that I use in a system.
The fan horizontaly, draws ambient air up through a 6mm (int.dia) tube. As the length of the pipe increases I expect the flow rate to drop as the pressure increases as shown in the data sheet (attached).
My question is, how can I work out the flow rate for different lengths of tube, say 1m, 3m, 5m, 10m, when the pressure of the fan is not constant?
Thanks in advance!
