An experiment has been performed to determine the porosity of an unconsolidated sandpack. distilled water was poured into a graduated cylinder to a height h,. fine sand of average grain size of 150 μm was poured into the cylinder to a height h, to from the sandpack. it was found that the water in the graduated cylinder rose to a height h, after the sand was poured into the cylinder. a) dewe the expresf the sandpack in terms of h, and h, b) given h,-5 cm and h.-8 cm, calculate the numerical value of the sandpack.
