Hello,
I am looking for help sizing an expansion tank for a chilled water system. It is an exsisting system and I don't know exact fluid content. Do I need to do a dilution test to get a accurate messurement. Can I just overestimate?

Expansion tank shall be kept at topmost level of the chilled water circuit.ideally it is better to calculate the total holding capacity of circuit .As a rule of thumb around 3% of the flow rate is adequate for expansion tank if it is chilled water system
Document here has tables and calculations for sized expansion vessels.

Here is software for such calculations.
THANKS Guys knew you could help
