Bulk Density Calculator:
Enter the values of dry soil weight, DSW(g) and soil volume, SV(cm3) to determine the value of Bulk density, BD(g/cm3).
Bulk Density Formula:
Bulk density represents the mass of particles within a given volume, including the space between the particles.
Bulk density indicates how compact or dense a material is when packed together, factoring in the spaces between the particles. It is influenced by both the material’s inherent density and the way particles are arranged or packed.
Dry soil weight represents the weight of the actual material, excluding the weight of any air or water trapped within.
Imagine packing the material as tightly as possible without crushing it. The soil volume represents the space occupied by the solid particles themselves.
Bulk density, BD(g/cm3) in grams per cubic centimetre is calculated by dividing the dry soil weight, DSW(g) in grams by soil volume, SV(cm3) in cubic centimetre.
Bulk density, BD(g/cm3) = DSW(g) / SV(cm3)
BD(g/cm3) = bulk density in grams per cubic centimetre, g/cm3.
DSW(g) = dry soil weight in grams, g.
SV(cm3) = soil volume in cubic centimetre, cm3.
Bulk Density Calculation:
- Find bulk density:
Given: DSW(g) = 500g, SV(cm3) = 250cm3.
Bulk density, BD(g/cm3) = DSW(g) / SV(cm3)
BD(g/cm3) = 500 / 250
BD(g/cm3) = 2g/cm3.
- Find soil volume:
Given: DSW(g) = 1000g, BD(g/cm3) = 1.5g/cm3.
Bulk density, BD(g/cm3) = DSW(g) / SV(cm3)
SV(cm3) = DSW(g) / BD(g/cm3)
SV(cm3) = 1000 / 1.5
SV(cm3) = 666.67cm3.
