# Wet Bulk Density of Soil

Written by Jerry Ratzlaff on . Posted in Geotechnical Engineering

Wet bulk density of soil, abbreviated as $$Y_{sat}$$, is the ratio between the total mass of soil and the total volume of soil.

## Wet bulk density of soil formulas

 $$\large{ Y_{sat} = \frac { m_l \;+\; m_s} {V_t } }$$ $$\large{ Y_{sat} = \frac{ G_s \;+\; e }{ 1 \;+\; e } \; \rho_w }$$ $$\large{ Y_{sat} = \frac{ G_s \; \rho_w \; \left( 1 \;+\; w \right) }{ 1 \;+\; e } }$$

### Where:

$$\large{ Y_{sat} }$$ = saturated bulk density of soil

$$\large{ \rho_w }$$  (Greek symbol rho) = density of water

$$\large{ m_l }$$ = mass of liquid

$$\large{ m_s }$$ = mass of solid

$$\large{ G_s }$$ = specific gravity of soil

$$\large{ V_t }$$ = total volume of soil

$$\large{ e }$$ = void ratio

$$\large{ w }$$ = water content
