Bulk density

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”…

Table 2.1: Parameters of tested water turbines (by Shionoet.al, 2002) Solidity (σ) Chord length (C) (mm) Blade inclination angle(ɸ)(°) Height (h) (mm) 0.20 62.8 43.7 300 0.30 94.2 43.7 300 0.40 125.7 43.7 300 0.50 157.1 43.7 300 0.40 125.7 50.0 374 0.40 125.7 60.0 544 Next, the effect of solidity σ on the water turbine characteristics was measured. Figure 2.1 shows a comparative analysis of torque characteristics for different solidity ratios at velocity 1.0 m/s, performed by Shionoet.…

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…

Density of Sand The objective of this lab is to use knowledge from previous labs, like the density of water and solids lab, and apply it to find the density of sand. First you must weigh your graduated cylinder, and record the weight, then pour in whatever amount of sand you choose. You then must weigh that to find the mass, and subtract whatever you got by the mass of the graduated cylinder. After that you pour in some water, and find the difference of how much the water went up and, what the…

When comparing the results of each subject in a group, they show that the control, or the subject that had no fluid intake during the experiment had very less or no fluid output in every 20 minutes unlike the subject that had about 5ml/kg-1 of water intake. The results also show that caffeine and exercise affect the amount of urine produced in different ways: the caffeine seems to increase the total amount of urine that is produced while exercise decreases the total amount of urine produced.…
