I would like to get some help regarding sizing a pump.
I'm working on a project in which we want to select a pump to generate a flow through a rectangular channel whose two ends (the inlet and outlet) are connected by a pipe. We want to place this pump at (near) the inlet port of this channel.
We will be filling this pipe with water of a volume around 1 liter. And we want to circulate this water through the rectangular channel (Imagine the 1 liter volume of water just entering the inlet port of the channel and exiting from the outlet port and doing this action for say 24 hours). There will not be any extra volume added or removed, just the set volume of water requires to be circulated.
The inlet and outlet ports and the pipe connecting them are at the same elevation (they are all in a horizonal plane/imagine them to be placed on a bench top). The pipe diameter would be around 3/8", the pipe length is lets assume 14 feet. (Please note that the numbers are only for me to learn the technique to solve for my actual system).
So, I would like to request if someone can help me decide how to find the pump size? or do you recommend any pump which you may have used/come across?
