WebEthylene glycol-based fluids are less viscous than propylene glycol-based fluids. Therefore, they generally provide superior heat transfer efficiency and better low temperature performance and are preferred for most heat transfer applications.

WebThe Prandtl number of many inorganic gases is approximately 0.70, as summarized in Table 7.5. It is much higher for liquids and the variation from one liquid to another is also greater: the Prandtl number of acetone is 4.5 at 20 °C, while it is 350 for ethyl ether. It equals 0.015 for mercury. Thermal diffusivity dominates in the case of mercury.

WebThe common name ethylene glycol literally means “the glycol derived from ethylene .”. Ethylene glycol is a clear, sweet, slightly viscous liquid that boils at 198 °C (388.4 °F). Its most common use is as an automotive antifreeze. A 1:1 solution of ethylene glycol and water boils at 129 °C (264.2 °F) and freezes at −37 °C (−34.6 °F ...
