Ethylene glycol vs water
WebViscosity. PG is more viscous than EG, this difference is especially noticeable at lower temperatures where viscosity increases. When operating at ~170°F the viscosity difference between EG and PG is about 10% and generally unnoticeable. At colder temperatures and start up conditions, PG will require significantly more energy. WebApr 8, 2024 · Milli-Q water and ethylene glycol were used as solvents for these studies. A 1 mL Hamilton syringe (Hamilton Company, Reno, Nevada) was used and the droplet size was 1 μL. The contact angle was measured immediately after the drop was delivered on the surface. The value of the contact angle was represented by the average of 10 …
