Extract of sample "Hydraulic Conductivity as Source of Error"

Although within a laboratory, slight measurement errors may possibly take places, such as hydraulic conductivity’s scale measurement due to inaccuracy in the 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 practised 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 like animal burrows, gravel lenses and root holes, may be absent in laboratory specimens. As a consequence, the field scale hydraulic conductivity is necessary to be measured in situ employing field methods like the sealed double-ring infiltrometer.
Conclusion
Hydraulic conductivity or permeability in soils has been recognized as one of the most essential parameters that direct the performance of a mass of civil engineering phenomenon and structures; yet most difficult to predict. Although the field data provides a better representation of hydraulic conductivity of soil as a large variety of sample may be drawn and the results can be considered to have greater representation while the lab data although having the accessibility to test via a variety of tests may lack the ability to be a representative of field soil.

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... that...

HYDRAULIC FRACTURING

...conducted gas fracturing within Lancashire. However, when earthquakes occurred within this area, the ban was introduced. 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 conductivity

...? Hydraulic conductivity and Hydraulic conductivity Introduction Hydraulic conductivity is the simplicity of water movement, through fractures and porous spaces in rocks or soil, and the level is determined through the computation of the location’s hydraulic gradient and the conditioning of the permeability, as well as the saturation of the material. Hydraulic conductivity is universally determined through an empirical approach, which entails correlating hydraulic conductivity to the properties of the soil. It is also determined through an experimentation process, entailing the calculation of the level of conductivity, experimentally (Deb &, Shukla, 2012). This paper will define hydraulic conductivity and discuss the properties... or the...

...It's the fact of common knowledge; beta-coefficient shows that while increasing average market profitability on pct, this share profitability will increase on beta pct. Look at sorted table on the Sheet 2. You see that 7 companies have Beta<1. It means that their shares are less sensitive to market fluctuations than other 8, who have Beta>1. Also we have C-coefficient values In our CAPM-model in perfect case we have C=0. For each company C values are small enough, what approves the adequacy of our model. Besides, we have Standard Errors of the Beta and C means. In fact, Standard Error of the mean quantifies how accurately we know the true mean of the population. In our case Standard Errors are very small - a good confirmation of correct C... and Beta calculation. The Root Mean Squared Error (RMSE) The mean-squared...

Hydraulic Machines

...of the hydraulic turbine. Pelton wheels are the generally preferred turbines for hydro-power, when the available water source has relatively high hydraulic head at low flow rates. Pelton wheels are manufactured in various sizes. The largest units can be up to 200 megawatts. The smallest Pelton wheels are only a few inches across, and can be used to tap power from mountain streams. Depending on water flow and design, Pelton wheels operate best with heads from 15 metres to 1,800 metres. They are found to exhibit high efficiency in high head applications and hence, more power can be extracted from a water source with high-pressure and low-flow than from a...

Hydraulic fracturing

...impacts of “hydraulic fracturing” include contamination of aquifers and ground water. By far, this is the most serious local environmental concern and possibly the most controversial concern. The potential threat to ground water comes from two sources namely the pumped fluid comprising of the mixture of water plus chemical, surface spills and the released natural gas. Secondly, chemical additives impact. Indeed, defining the acidic level of additives used in the fracking phase should be rather modest and measurable scientific duty; nevertheless, in some countries fracking enterprises are under no lawful obligation to proclaim the correct alignment of this mixture. The third impact is blow outs whereby...

Source of error

...Identification of the Sources of Error in Newton’s Second Law. Newton’s second law of motion prompts that there is no state of balance between the action of objects and the existing force that surrounds them .It also argues that the speed of an object is reliant on two variables, the net force acting on an object and the mass of an object (Browne 58).Generally as the force acting on an object is elevated, the speed of the object increases, and as the mass is elevated, the speed of the object is decreased. Formally, the law argues that the acceleration of an object as a result of net force is absolutely correspondent to the intensity of the net force, in the similar direction of the net force and...

Hydraulic fracking

...Hydraulic Fracking To UK Legislation Assembly Legislation.gov.uk 23/4 Dear Politicians The aimof this letter is to persuade UK politicians to lobby for adoption of hydraulic fracking as alternative energy source. The world is facing energy crisis due to globalization, man-made effects and climate effects that has rendered fossil energy sources insufficient. This has led to economies to seek alternative energy sources in order to be abreast with crisis management. UK is one of the economies that is experiencing the energy crisis and seeking alternatives. Fracking process that involves extraction of shale gas has been a project encouraged by the government...

...torque on the body, the net torque has to be calculated. The net torque is the sum total of all the individual torques acting on the body. However, since this is a rotational equilibrium, the addition of all torques acting on a body results to zero. This implies that net torque does not exist on a body (Benenson and Stöcker). Sources of error In the experiment, there is a difference in theoretical and experimental values. Percentage error for F1 is 0.75 and the percentage error for F2 is 1.6. The errors are attributed to various reasons. The meter stick may be having a non-uniform distributed mass, thus resulting to the errors. This is...

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...
