Download file to see previous pages This paper will define hydraulic conductivity and discuss the properties or the states that affect the levels of hydraulic conductivity. Further, the paper will explore the importance of hydraulic conductivity and the methods used for the determination of hydraulic conductivity using empirical-based, field-based and lab-based approaches. The properties and the states that affect hydraulic conductivity The first property is the compaction conditions of the soil or the rock materials, where the difference in hydraulic conductivity depends on the contours of initial saturation. The zones of initial saturation are computed using the following equation: (Brauns, Bieberstein & Reith, 2003) Under the equation, “w is the molding water level; yd is the weight of the dry unit of the soil, yw is the (per-unit) weight of water, and Gs is the particular gravitational level of solids” (Brauns, Bieberstein & Reith, 2003). Defining the water levels in the combination and the weight of the dry unit matches the hydraulic conductivity. The second determinant of hydraulic conductivity is index properties, which is marked by the composition of the soil or the rock material in question. ...
d of larger particles, which are ordinarily less likely to be closely compacted into double layers, levels of hydraulic conductivity are lower (Beckie & Harvey, 2002). The third factor is the atterberg limits of the materials at the given area, where hydraulic conductivity should take place. In general, hydraulic conductivity reduces where there is an increase in the plasticity index and the liquid limit. This is the case, because plastic index and liquid limit are directly connected to the mineralogy of the soil, clay or the rock material in question. Sometimes, an increase in the clay content of a soil or rocky material or the presence of more active minerals of clay leads to a reduction in the size of microscale pores (Deb & Shukla, 2012). These microscale pores are the ones that determine the flow of water in the compacted wet lines of the soil or the rocky materials. This factor implies that soils with higher plasticity index and liquid limits will contain more clay content or active clay minerals, and will characteristically have lower levels of hydraulic conductivity (Ganjian et al., 2006). Also, the particle size distribution of materials influences the hydraulic conductivity of the given material. This means that an increase in the percentage level of the fine particles contained in a unit area of the material causes a decrease in the hydraulic conductivity of the material. For example, soils with high levels of fine clay tend to have lower conductivity levels (Deb & Shukla, 2012). Why hydraulic conductivity is so important Hydraulic conductivity is used for different roles, including the development of engineering models entailing the use of geotechnical designing. Under this use, hydraulic conductivity is necessary for the determination of retaining ...Download file to see next pagesRead More

Radiation and Thermal Conductivity

...?Summary The essence of the experiment was to establish the general characteristics governing thermal radiation and thermal conductivity. The experiment was divided into four parts in order to conduct studies related to these characteristics. The set up for the first experiment involved a radiometer and an emitter and the general realization was that a direct proportionality between heat influx from the emitter and the view factor and energy transmitter. The second experiment was aimed at looking at how the intensity of radiation varied with distance. The general realization was that there existed an inverse proportionality between the intensity of radiation and the square of the distance covered by the radiation from the source... of the...

In other places within South America, hydraulic fracturing has not yet been exploited. However, it is believed that countries such as Brazil could enhance their economy by undertaking in this mining process Economic Impact of Hydraulic Fracturing Hydraulic fracturing enhances economic growth in various ways. One, having Shale gas and oil makes a country to be more energy independent (“Presidents Economic Report for 2012”, pg 256 2012). Consequently, such a country will reduce the amount of expenditure incurred in importing oil. Similarly, when mining...

Hydraulic Machines

...of the vane = Work done per second Kinetic energy per second Operating principles of common turbomachines Introduction Turbomachines or turbines are defined as the hydraulic machines which convert hydraulic machines into mechanical energy. This mechanical energy is used in running an electric generator which is directly coupled to the shaft of the turbine. If the water flows parallel to the axis of the rotation of the shaft, the turbine is known as axial flow turbine. If the head at the inlet of the turbine is the sum of pressure energy and kinetic energy and during the flow of water through runner a part of pressure energy is converted into kinetic energy, the turbine is known as reaction...

Hydraulic machines are those machines which convert hydraulic energy into mechanical energy (further converted into electrical energy) or mechanical energy into hydraulic energy. The former types of machines are called turbines and the latter, pumps. Impact of a Jet onto a vane A combination of both pump and turbine is used in fluid couplings and torque converters for the transmission of power smoothly through a fluid medium. The analysis of impact of fluid jets on vanes is typically involved in the design of an efficient turbo-machine. When a vane moves away from...

Hydraulic Conductivity as Source of Error

...Sources of Error & Conclusion: Hydraulic Conductivity Sources of Error Although within a laboratory,slight measurement errors may possibly take place, such as hydraulic conductivity’s scale measurement due to inaccuracy in measurement of volume, time, length or weight. Some of the possible errors are The most probable error is in the way the laboratory measurements are practiced in field conditions. The value of “k” as measured in the laboratory may be some orders of scale less than real large-scale field values. As the specimens within the laboratory are not constantly representative of conditions of the field, and macroscopic attributes that manage field permeation...

Hydraulic fracturing

...“Hydraulic fracturing” or “cracking” is a process of through which natural gas and oil are extracted from rocks thatare deep below the earth’s surface. The process entails injecting massive quantity of water, sand and chemicals at an explosive pressure for the rocks to crack.. The pumped fluid contains tiny particles of solid materials known as proppants, which prop up the fractures to open once the production process begins. Additionally, the hydraulic fracturing fluids is usually water-based and contain different chemicals, as well as bactericides among others to promote the efficiency of the fracturing process and stop damage from taking place. After hydraulic fracturing, the pressure...

Ph conductivity lab

...PH Conductivity Lab Conductivity measurements for various solutions were determined using a conductivity meter. The concentrations of solutions of unknown concentrations of NaCl were determined using a calibration curve of conductivity of samples of known concentrations. This was made possible by obtaining the equation of the line of best fit of the calibration graph and substituting values appropriately. Using this approach, the concentration of the NaCl solutions could be directly determined. The PH of various solutions was also measured using an electronic PH probe, red and blue litmus paper, universal PH indicator paper and red cabbage. The colour change in observed...

Hydraulic Conductivity in Soils

...Hydraulic Conductivity in Soils Hydraulic Conductivity in Soils Bi-modal soils are the soils that have structural and matrix porosity (Dexter & Richard, 2009). In these bi-modal soils there is a model for water retention which is developed into other models such as the tri-modal soils (Dexter & Richard, 2009). Such a change ensures there is an incorporation of the existing effects of macro-pores. Additionally, the bi-modal soil model has its basis on the idea of water retention function of the exponential Boltzmann. Researchers also believe that the model can also extend to include other numbers such as the “n” of the modes of porosity. These modes exist because the soil structure is usually hierarchical. It is also used together... with...
