I wish to add Glycol to existing ch
(OP)
I wish to add Glycol to existing chilled water circulation system to protect against freezing. The percentage of Glycol to the full system water volume is 20%
What effect will this have in terns of increased pressure drop and specific heat capacity.
Is there a percentage that can be is added to the friction losses of the standard pipe sizing data that makes allowance for any effect that the Glycol will have upon the system.

Try this link..... you should be able to get the thermal properties info that you need
www.dow.com/heattrans/fluid/fluid2.htm
The short answer to your question is.... "not much change at 20%".... the thermal properties of Glycol (ethylene or propylene)are not that much different than water
Good luck
