    Laboratory Report 2: Soil Texture, Bulk density and Porosity Introduction Soil Texture The classification of soil texture is determined by the percentage of each of the soil separates. Soil separates are mineral particles smaller than 2mm, and these particles are sand, silt and clay. These textures are separated by the size of the particles, with sand being the largest between 2mm and 0.05mm, silt at between 0.05mm and 0.002mm, and clay at <0.002mm. The size of the particles influences the porosity and other characteristics of the soil. The soil texture determines the fertility of the soil, its water holding capacity and how the soil can be managed. The purpose of this lab was to become familiar with determining soil texture by using various methods. Particle Density and Bulk Density Particle density is the measure of the density of the soil solids, with no pore space. This is important as it helps increase understanding of the soil texture and helps to determine the bulk density and porosity. Bulk density is the measure of relative soil compaction, as expressed in total mass per total volume. This helps determine the porosity of the soil and how compacted the soil is. As the bulk density increases so too does the compaction of the soil and the porosity decreases. The purpose of the lab was to…

    Material bulk engineering properties such as angle of repose, bulk density, grain to grain angle of internal friction and cohesion can be easily be measured from laboratory tests and related to grain-machine interaction systems responses where the micro parameters in DEM models are developed using particle-particle friction, particle-geometry friction and the particle density to simulate material behavior (Asaf et al., 2007). The particle size and shape distribution are also considered to be…

    III. RESULTS AND DISCUSSION A. Influence of specific gravity to water to binder ratio of M-S-H binder In development of M-S-H binder with magnesium oxide and silica fume, it is noted that silica fume has rather low specific gravity (S.G) and bulk density compared to Portland cement (PC). Thus, use of high silica fume content in the binder consequently results in a binder system of low specific gravity and bulk density, compared to PC. The light weight binder leads to a difference in water to…

    One of the topics covered deals with salinity and temperature. As part of the lesson, students will essentially understand how (1) temperature and salinity affect water density and (2) how those previously mentions characteristics affect how heat moves globally. This lesson comes toward the end of the oceanography unit in the class. In days prior, students have learned about waves, tides and currents. For the lesson students are required to take their knowledge from the unit to “layer”…

    3.2 Analysis of chip formation Fig. 7 shows the chip forms obtained during milling of the Al7075 (a) and MMCs (b) using the uncoated carbide inserts at a feed rate of 0.1 mm/tooth, machining speed of 290 m/min and axial depth of cut of 1.3 mm. The Al7075 chips formed during milling exhibited a smooth and shiny surface, and were in a semicircular and parabolic trapezoidal wave with a small radius and a saw-tooth-form, as shown in Fig. 7 (a). Fig. 7 (b) shows the chip shapes formed during the…

    In the “ If the earth has layers than the top layer is the least dense.” the hypothesis was accepted. Data that supports this is that canister number one had the least amount of sand and a density of 0.40g/mL3.This canister was the least dense of the three canisters. This is why it floated on the surface of the water. Opposed to canisters numbers two with more sand than canister number two and canister number three had the most sand .Water’s density is 1 g/mL3 . The reason canister one floated…

    the left is the SD and the one on the right is the %RSD. x ̅= (∑▒x_i )/n S=√(〖∑▒〖(x_i-x ̅ 〗)〗^2/(n-1)) %RSD=(S x 100%)/x ̅ Lastly, in order to be able to convert from mass to volume and vice versa, an equation that relates the two is required. The following formula is used to calculate density: d=m/v, where m is mass and v is volume. Analysis # of additions of water to the 100 mL beaker Mass of each portion of water added by the 50 mL beaker Mass…

    Equity focuses on the distribution of resources in an “equal” and fair way amongst the members of a society. Efficiency, is defined as the optimal production and allocation of resources. While at first glance, these terms may be hard to grasp, if you take a look at the Canadian dairy farm industry, you will see a great example of how these terms unfold in reality. It illustrates the outcomes of the market when each is in play. To glean a closer look at the effects of efficiency and equity on…

    Introduction and Theory: The lab conducted was to investigate the density of not only copper but also diet and non-diet soda. Techniques used in the experiment included water-displacement, measuring copper’s dimensions, and using volumetric pipettes to measure out specific soda volumes. Beginning Question(s): How does the use of two experimental methods, improve the chances of calculating the density of copper? How does the density of non-diet soda compare to that of diet soda measured at…
