**Given data:**
- Oven dry weight of the rock sample = 0-655 kg
- Weight of the rock sample after saturation with kerosene = 0-732 kg
- Weight of the kerosene displaced by the rock sample = 0-301 kg
**Calculating the volume of the rock sample:**
The volume of the rock sample can be calculated using the equation:
Volume = (Weight of kerosene displaced) / (Density of kerosene)
The density of kerosene is assumed to be constant at 0.8 g/cm³.
Converting the weight of the kerosene displaced to grams:
Weight of kerosene displaced = 0-301 kg * 1000 g/kg = 0-301000 g
Calculating the volume of the rock sample:
Volume = (0-301000 g) / (0.8 g/cm³) = 0-376250 cm³
**Calculating the total volume of the rock sample:**
The total volume of the rock sample can be calculated using the equation:
Total Volume = (Weight of the rock sample after saturation) / (Density of kerosene)
Converting the weight of the rock sample after saturation to grams:
Weight of the rock sample after saturation = 0-732 kg * 1000 g/kg = 0-732000 g
Calculating the total volume of the rock sample:
Total Volume = (0-732000 g) / (0.8 g/cm³) = 0-915000 cm³
**Calculating the porosity:**
Porosity is defined as the ratio of the void volume to the total volume of a material.
Porosity = (Total Volume - Volume) / Total Volume * 100%
Substituting the calculated values:
Porosity = (0-915000 cm³ - 0-376250 cm³) / 0-915000 cm³ * 100% = 0-538750 cm³ / 0-915000 cm³ * 100% = 0-588% * 100% = 30.5%
Therefore, the porosity of the rock sample is 30.5%.
**Answer:**
The porosity of the rock sample is 30.5%. (3)
- Oven dry weight of the rock sample = 0-655 kg

Therefore, the porosity of the rock sample is 30.5%.
**Answer:**
The porosity of the rock sample is 30.5%. (3)
