Exercise 4

Part 1: A completely saturated sample of sandstone has a bulk density of 2.61 g/cm3, an effective porosity of 10 percent, and a total porosity of 12 percent.

Determine the density of the solid phase (i.e., the density of the mineral).

Part 2: One cubic meter of quartz sand has a dry mass of 2,320 kg.

  1. Calculate the porosity of the sand.
  2. Calculate the mass (in kg) of the sand for the following degrees of saturation: 25 percent, 75 percent, 100 percent.

Part 3: A sample of quartz sand has a dry mass of 753.7 kg and a volume of 0.36 m3.

  1. Calculate the porosity of the sand.
  2. Calculate the mass (in kg) of the sand assuming a degree of saturation equal to 62 percent.
