a. 100 cm3 saturated sample of quartz sand is weighed, gravity drained, weighed, oven dried, and weighed again. The saturated, gravity-drained, and oven-dried weights are 130g, 110 g, and 105 g, respectively. Using these data, calculate the following quantities. i. Dry bulk density ii. Porosity iii. Degree of saturation after gravity drainage iv. Specific yield
