10. It is required to determine the water content of a wet sample of silty sand weighing 400 g. This mass of soil was placed in a pycnometer and water filled to the top of the conical cup and weighed (M3). Its mass was found to be 2350 g. The pycnometer was next filled with clean water and weighed and its mass was found to be 2200 g. Assuming G = 2.67, determine the water %3D content of the soil sample.

Consider that a 58.7 gram sample of dry soil is used in making a mechanical analysis by using the hydrometer method. The laboratory was held at a constant temperature of 20 C (68 F). The 40 s hydrometer reading was found to be 32.5 and the 8 hr hydrometer reading was 15.5. The percentage of sand in this soil sample is (note, a 58.7 gram sample is used here): Your Answer: Answer units

1.4 A test for the relative density of soil in place was performed by digging a small hole in the soil. The volume of the hole was 400 ml and the moist weight of the excavated soil was 9 N. after oven drying, the weight was 7.8 N. Of the dried soil, 4N was poured into a vessel in a very loose state, and its volume was found to be 270 ml. The same weight of soil when vibrated and compacted had a volume of 200 ml. Determine the relative density.
