(c) A dam project will be constructed in the Kenyir area. The laboratory test results on a saturated soil test being used indicated that it has the initial and final volume is 24.6 cm and 15.9 cm?, mass of wet soil (mi) is 44 gm and mass of dry soil (m2) is 30.1 gm. Based on the data given, determine the shrinkage limit of the soil.
Following data are given: 1. Available moisture holding capacity of soil-12.5cm/m depth of soil 2. Root zone depth of crop=0.8m 3. Consumptive use=5mm/day If moisture depletion is allowed to 50% of available moisture then the frequency of irrigation will be ___days.
Q3) If; the field capacity and wilting point are 30% and 10%, respectively, the dry unit weight of soil is 1.4 gm/cm3, and depth of root zone is 1.Om.The equivalent depth of moisture content available of .evapotranspiration is * 280 mm O 300 mm O 350 mm O 100 mm (
5. The weight of a sample of partially saturated soil 600 g with a volume of 365 cm3 and after drying the weight became 543 g and the specific gravity of the solids 2.67 Calculate: 1- Water or moisture content 2- Void Ratio 3- degree of saturation 4- If the soil is saturated later without changing the volume, calculate the unit weight for it.
In natural state, a soil weighs 3500 lb/cy. The same soil has a load factor of 0.83. a. What is the unit weight of the soil in its loose state? b. A contractor has seven (7) Caterpillar 725 articulating trucks available to haul this same soil to a project that requires 55,000 ccy of the soil. In the compacted state, the soil weighs 4300 lb/cy. Each Caterpillar 725 has a maximum haul capacity of 17 lcy. Currently the project schedule only accounts for each truck hauling no more than 550 loads to the site. Based on the maximum capacity of the Caterpillar 725, can this schedule requirement be met?
