A sample of silty sand in its natural conditions had a volume of 120cm3 and weighed 149g. After saturating the sample with water, it weighed 188g. The sample was then drained by gravity until it reached a constant weight of 133g. Finally the sample was oven dried for 2 days at 221 degrees fahrenheit after which it weighed 120 g. Note that the volume of the voids in the sample under natural conditions is the volume of water in the sample at saturation. Assuming that the density of water is 1 g/cc. Perform the following calculations: a) Water content on a mass basis under natural conditions b) Specificyield c) Specific retention d) Totalporevolume e) Porosity under natural conditions
