Reservoir Sizing - Rule of Thumbs
Reservoir Sizing - Rule of Thumbs
(OP)
Hi,
I would like to determine an adequate size of a glycol reservoir that will be used in closed circuit as the cold fluid in a fuel/glycol heat exchanger. The flow rate required in the glycol line is 20 GPM. There is a quantity of 15 Gallons of fluid required to fill the pipes. Are there any rules of thumbs in terms of an adequate size for the reservoir? I heard that 3 times the flow rate is a rule of thumb. Please provide references.
Thank you,
Gabriel

RE: Reservoir Sizing - Rule of Thumbs
Sizing a reservoir can have several design considerations, often a combination of criteria to be met:
1. If the reservoir is for a pump suction with an exposed free surface, then fluid flow intake design criteria is applicable. The Hydraulic Institute Manuals discuss this complex problem of submerged suctions, vortex problems, etc.
If the reservoir is to serve as an inventory storage with the system operation variables (same as a conventional expansion tank), then the system volume, temperature ranges, pressure ranges, and expansion/contraction character of the fluid, fluid containers, and the piping need to be considered. See comments on "Heat Transfer & Thermodynamics" section, under "expansion tank" topic.
The reservoir may be designed to allow for some system leakrate before replenishment, to allow initial fill with standard purchased container sizes, etc. These O&M criteria may dominate the design.

RE: Reservoir Sizing - Rule of Thumbs
The system is like this : There is tank from which a pump is used to pump fluid through a pipe line to a heat exchanger. Then this fluid that passes through that heat exchanger is sent back to the tank. The system is not pressurized because the tank is open to the atmospheric pressure.
I hope this can help in terms of the sizing.
Thanks
Gabriel
