When selecting a window for an engine test cell, you generally need to consider blast, pressure, fire and noise resistance. The properties of the window (and doors) need to be matched to the properties of the wall, else one component may compromise performance of the entire structure.

Prex,
Thank you. I did search on the Internet quite a bit but under "thermal expansion" and "glycol", and didn't think to try "brine".
I'm still missing something, though. Several sources list the volume coefficient of thermal expansion (Beta) for water at 20C...
I need the coefficient of thermal expansion for a 50% mixture of ethylene or propylene glycol in water from 20 to 95C. I have found values for 100% glycol (650 to 700E-6 per degree C), and water is about 200E-6. Would it be correct to average the values for 100% water and 100% glycol?
