Soil in a 2.000 m wide x 2.000 long and 1.125 m deep container weighs 7,435 kg (7.435 x 103 kg) when completely dry. The soil is watered until it is fully saturated. After several days the soil drains to field capacity and weighs a total of 8,473 kg (8.473 x 103 kg). Assuming the density of 2650 kg/m3 (2.650 x 103 kg/m3 ) for solid rock (ρr) and 1000 kg/m3 (1.000 x 103 kg/m3 ) for water (ρw), determine the following values

Question
Soil in a 2.000 m wide x 2.000 long and 1.125 m deep container weighs 7,435 kg (7.435 x 103 kg) when completely dry. The soil is watered until it is fully saturated. After several days the soil drains to field capacity and weighs a total of 8,473 kg (8.473 x 103 kg). Assuming the density of 2650 kg/m3 (2.650 x 103 kg/m3 ) for solid rock (ρr) and 1000 kg/m3 (1.000 x 103 kg/m3 ) for water (ρw), determine the following values:
1) • Dry soil: bulk density (kg/m3 ) and porosity (%)
2) • Saturated soil: mass (kg).
3) • Field capacity soil: degree of saturation (%) and volume wetness (volumetric water content) (%).
