Rock Density Calculator
Calculate bulk density and porosity of a rock sample from dry mass, volume, and grain density.
How to Use the Rock Density Calculator
- Enter the dry mass of the sample in kg.
- Enter the total sample volume in m³.
- Enter the grain (mineral) density in kg/m³.
- Click Calculate for bulk density and porosity.
使用例
- •Petrophysical analysis
- •Rock core studies
- •Geology research
計算式
ρ_bulk = m / V; porosity = (V − m/ρ_grain) / V × 100%
