Description
bulkVolume = (saturatedMass-submergedApparentMass)/density; accessiblePoreVolume = (saturatedMass-dryMass)/density; accessiblePorosity is their ratio.
Rock and sediment material properties depend on pore, fluid, solid and bulk-volume bases. A porosity or saturation ratio assumes compatible masses, densities and measurement conditions; it does not validate those assumptions.
bulkVolume = (saturatedMass-submergedApparentMass)/density; accessiblePoreVolume = (saturatedMass-dryMass)/density; accessiblePorosity is their ratio.
When to use this tool
Use Rock Sample Buoyancy Corrected Volume Term when checking a supplied material-volume or composition balance.
How to use the tool and how it works
- Enter dryMass, saturatedMass, submergedApparentMass, liquidDensity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read bulkVolume, accessiblePoreVolume, accessiblePorosity. Use the output convention below.
Require positive liquidDensity, saturatedMass >= dryMass >= submergedApparentMass and saturatedMass > submergedApparentMass. bulkVolume = (saturatedMass-submergedApparentMass)/density; accessiblePoreVolume = (saturatedMass-dryMass)/density; accessiblePorosity is their ratio.1

}Limitations and assumptions
- Masses use one balance convention and liquid state. Buoyancy, saturation and accessible-pore assumptions are supplied; air corrections, closed pores and specimen reaction are omitted.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use appropriate specimen methods and complete material models for physical interpretation, uncertainty and practical engineering use.
