I'm new at plastic extruding and am looking for the expansion rate of a 70/30 ethylene glycol water mix for an expansion tank. I've worked out the pressures and flow but cannot find the proper volume for a reservoir tank for expansion from ambient to approximately 320 degrees f.

a calculated pressure for 320 degrees at 70/30 mix at ideal conditions would be 28 psi. They are running the pumps at about 50 psi, hence a blown flexible hose is almost lethal to anyone in proximity. I designed a circuit to shut down the pump on any pressure loss, but at 50 psi the burst is still substantial before shutdown. I hate adding more things because the more you add the more can go wrong. My background is maintenance and I try and and make it simple to troubleshoot.
