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?

WebWater is the most important exception to this rule. Water expands with increasing temperature (its density decreases) when it is at temperatures greater than 4ºC (40ºF). However, it expands with decreasing temperature when it is between +4ºC and 0ºC (40ºF to 32ºF). Water is densest at +4ºC. (See Figure 3.)

However, it … The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically, it measures the fractional change in size per degree change in temperature at a constant pressure, such that lower coefficients describe lower propensity for change in size. Several types of coefficients have been developed: volumetric, area, and linear. The choice of coefficient depends on the particular application and which dimensions are consid…
