Calculating the needed height for reservoir
Calculating the needed height for reservoir
(OP)
Hi all,
I have a system as shown in the schematic (see attachement).
The reference height is z=0, number 1 and 3 are reservoir. The use of upper reservoir (nr. 1) is to damp the pulsation of the pump. I want to calculate the height so that the flow rate inside my channel (nr. 2) is according to the necessary reynold number. The upper reservoir is supplied by a flow from a pump.
I use bernoulli equation at upper and lower reservoir. Is it the correct way to do that? I can calculate the losses in my system (nr. 2) including the loss along the pipe.
Thank you.

RE: Calculating the needed height for reservoir
Your liquid shall flow from 1 to 3 and pass 2, right? 1 shall act as a pulsation dampener for the pump that feeds it. What kind of pump is that and what is the pressure of that pump? If you know that this pump must have a pulsation dampener, you will know this pump already. And if this pump requires a pulsation dampener, why will it not come from the supplier with dampener installed?
Are tank no. 2 and 3 pressuried?

RE: Calculating the needed height for reservoir
I know it might need a pulsation damper because of the pump is a positive displacement pump, is there anything wrong with my reasoning?
Thanks!

What about tank 2 and 3? Any pressure inside or just atmospheric pressure?
