##### Fuid Flow - Laminar Flow Problem
« on: December 22, 2008, 07:35:19 AM »
Hi all,

I a stuck on this problem, if you could point me in the right direction i would really appreciate this.

a process uses an oil of density = 800kgm-3 and a vis 80mPa.s at a flowrate of 0.72 m3hr-1. the feed pipe splits into two smaller pipes and both discharge freely into the process. One pipe has an inner diameter of 5cm and Length 20m while the other has an inner diameter of 2.5cm and a Length 10m

find the rate of flow in each of the smaller pipes....

so far all i have is if i could find a diameter of the feed pipe then i could use continuty equation to solve using the velocities. I am not sure however.

Thanks,
