Hi all,
I am designing a water circuit where water will be pumped around a cold water circuit. In order to protect the pumps a recirculation line will be installed where a % of the flow will be diverted in case there are any blockages downstream of the pumps.
Flowrate down the 2" main line pipe is about 10 m3/hr. I want to size the recirculation pipe for about 15% of the flow but need the velocity of the water in order to calculate the pipe size required for the recirculation line.
Can anybody advise? My gut is telling me this shouldn't be difficult but the answer seems to evade me!!! I have a feeling I need to two equations and then iterate them....
Many thanks in advance.
