Why it matters

What the numbers tell you

At 10 wt% and 20 °C, aqueous barium chloride has a density of about 1093 kg/m³ (1.093 g/cm³) — roughly 1.09× the density of water. It also has a dynamic viscosity of about 1.130 cP, against roughly 1 cP for water at the same temperature. Those differences carry straight into volume-to-mass conversions, pump and pipe sizing.

At 25 °C, 20 wt% barium chloride has a density of about 1201.5 kg/m³ and a dynamic viscosity of about 1.189 cP. At 25 °C, 24 wt% barium chloride has a density of about 1250.9 kg/m³ and a dynamic viscosity of about 1.287 cP.

Limitations

Before you use these numbers

▸Laliberte (2009) aqueous-electrolyte correlation for BaCl2-water, density and viscosity. Tabulated for 2-24 wt% over 15-60 degC. The 15 degC floor is the lower bound of the correlation's BaCl2 density data; the 24 wt% ceiling stays below the correlation's concentration limit and below saturation (barium chloride dissolves to about 26 wt% at 20 degC). Heat capacity is not tabulated (the correlation's BaCl2 heat-capacity data is a single 25 degC point). Concentrations are anhydrous BaCl2 by mass; the common dihydrate is about 85% BaCl2 by mass. Barium salts are toxic - handle per the supplier's safety data. Values are for preliminary design; verify against vendor data for critical service.
▸Values are tabulated only inside the 2–24 wt% and 15–60 °C ranges shown; the correlation is not extrapolated beyond them here.
▸Figures are for a pure barium chloride–water system. Commercial grades contain impurities (for example chloride in some caustic grades) that shift density and viscosity; check the supplier's data sheet for a specific product.
▸Use for preliminary design; verify for critical service.
