  1. (Porosity). A dry rock weighs 240 grams and has a bulk density of 2.4 grams per cubic centimeter. When saturated with pure water at room temperature (T=25°C), it weighs 250 grams. At room temperature, specific volume of water is 1.00295 x10-3 m3/kg. Calculate the porosity of the sample
  2. (Permeability). A cylindrical core sample of 1 cm length and 1 cm2 cross-section has upstream and downstream pressures of 2 atm and 1 atm, respectively, during steady state flow of water at 0.997 g/s at room temperature. Calculate the permeability of the core.                                                                                Note: Water @ 25°C, viscosity = 1 cp, density of water = 0.997 g/cm3.
