Ethanol–Water Mixture Density

Two tables · Full float64 precision · Temperatures: 15, 20, 25, 30, 35, 40 °C

Model: Wagenbreth–Blanke polynomial, OIML R•22 (1975), 54 coefficients. All density values are IEEE 754 double-precision floats (full float64 repr). Digits beyond ~12–13 decimal places are in the noise of float64 arithmetic and carry no additional physical information. All five validation spot-checks pass; maximum floating-point residual < 5 × 10⁻⁸ kg/m³.

Table 1

Density by mass fraction (% w/w)

Input: ethanol mass fraction in percent by weight. Each row gives the mixture density in g/mL at six temperatures, computed directly from the Wagenbreth–Blanke polynomial. No unit conversion or iterative solving is required — % w/w maps directly to the polynomial’s native input variable.

Table 1 — Ethanol-water mixture density (g/mL) vs. ethanol mass fraction (% w/w) at six temperatures. Computed from the Wagenbreth–Blanke polynomial (OIML R22, 1975). Valid range: 0–100 % w/w, −20 to 40 °C.

Table 2

Density by volume fraction (% v/v)

Input: ethanol volume fraction in percent by volume, defined at the reference temperature of 20 °C (OIML convention). For each % v/v value, the corresponding mass fraction is first solved by Newton’s method (converges in ≤4 iterations to full float64 tolerance), then the mixture density is evaluated at each temperature from the Wagenbreth–Blanke polynomial. The density at 20 °C is the native result; densities at other temperatures reflect the same mass fraction evaluated at different temperatures.

Table 2 — Ethanol-water mixture density (g/mL) vs. ethanol volume fraction (% v/v, defined at 20 °C reference temperature, OIML convention) at six temperatures. Mass fraction solved by Newton iteration from % v/v; density then evaluated by the Wagenbreth–Blanke polynomial (OIML R22, 1975).

Computed from the Wagenbreth–Blanke polynomial (54 coefficients) as published in OIML International Recommendation R•22 (1975), oiml.org. Coefficients: github.com/ququqem/wagenbreth-blanke-oiml-r22 · DOI: 10.5281/zenodo.19426888
