Math & Numbers
颗粒/多孔材料的体积密度与孔隙率。体积密度 ρ_bulk = m/V_bulk，三向反算（求 ρ、m 或 V）。可选填真密度 ρ_true → 孔隙率 ε = 1 − ρ_bulk/ρ_true。相对密度 = ρ_bulk/ρ_water。质量 kg、体积 m³、密度 kg/m³。

-d '{"solveFor":"density","density":0,"mass":1.6,"volume":0.001,"trueDensity":2650,"decimalPlaces":4}'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。
POST https://api.elysiatools.com/zh/api/tools/bulk-density-calculator| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| solveFor | select | 否 | — |
| density | number | 否 | Bulk (apparent) density in kg/m³. Required when solving for mass or volume. |
| mass | number | 否 | Mass of the material in kg. Required when solving for density or volume. |
| volume | number | 否 | Bulk volume (including voids) in m³. Required when solving for density or mass. |
| trueDensity | number | 否 | True (particle) density of the solid material itself, no pores. Optional — when given, porosity ε = 1 − ρ_bulk/ρ_true is reported. Quartz ≈ 2650, steel ≈ 7850 kg/m³. |
