Fluids / Propylene glycol, 20 % by volume

Specific heat of propylene glycol, 20 % by volume vs temperature

A 20 % by volume propylene glycol solution, freeze protection to about −7 °C — the corrosion floor: any leaner and the inhibitors are too dilute to trust.

Specific heat in kJ/(kg·K), from -5 to 100 °C. The chart and the table below are the same numbers; the table is the one you can copy.

Rows marked published land exactly on a source anchor and are the tabulated figure. The rest are this library’s interpolation between the two anchors either side — good enough to design with, and said out loud so you can decide that for yourself.
