    potential applications owing to their distinctivetwo-dimensional assembly and related band structure. Graphenehas gained attention of many scientists since its innovation due to its exceptional large surface area (2630 m2g_1),[11] high electrical conductivity at room temperature[12,13](106 s cm-1), good mechanical properties (~1.1 TPa), fracturestrength[14] (125 GPa), breaking strength[15] (42 N m-1), excellent mobility as charge carriers[16] (~20 m2 V-1 s-1 ), superior thermalconductivity (~5000 W

    feedstock material. By the investigation of fly-ash composition and micro-structure it shows terrific mechanical properties and good wear resistances due contain of oxides which can be utilised as proactive ceramic coating material and has low thermal conductivity (Satapathy et al, 2009). No pre-processing is needed because of its microstructure has spherical shape that makes the flow ability easy. Most importantly it’s very inexpensive when compared other feedstock materials used in other thermal spray

    CHAPTER 1 INTRODUCTION Composite materials are the engineering materials made from two or more constituent materials they remain separate and distinct on a macroscopic level but forming a single component or Composites can defined as materials that consist of two more chemically and physically different phases separated by a distinct interface(matrix phase and dispersed phase). The different systems are combined judiciously to achieve a component with more and more useful structural or functional

    Charleston, West Virginia area. First 30 years, it only operated in Kentucky and Ohio. Starting from 1997, Caprica carried on an expansion strategy to Michigan, and in 2005 it applied the hydraulic fracturing technology on shale gas exploiting. Up till now, Caprica already have five years experience on using hydraulic fracturing technology. Current Strategy: Caprica’s strategy is to grow its reserves, production, net income and cash flow. It is focus on acquiring properties that have development

    What is Hydraulic Fracturing Contrary to popular belief’s Hydraulic Fracturing is not a drilling process .It is the series of steps that are used after the drilling of hole in the ground is completed to create or restore small fractures or opening in the reservoir rock formation .These small fractures or opening in the reservoir are mainly used to extract –petroleum, natural gas ( such as shale gas , tight gas , and coal seam) ,water And natural substances This process was first used in 1947

    Contents Introduction 1 What is Hydraulic Fracking? 2 The Roberts Torpedo, 1864 3 Kelpper Well No. 1, 1947 5 Hydrafrac, 1949 6 The Growth of Hydrafrac, 1949 - 1954 8 Introduction Hydraulic fracking (‘Fracking’) dominates the US oil and gas industry. Although it is currently a politically dividing topic due to environmental concerns (United States Environmental Protection Agency, 2010), the concept behind fracking has been around for over 150 years (Roberts, 1866), and has been in

    Argument against Hydraulic Fracturing Hydraulic Fracturing is the process in which a borehole is made on earth, and the Shale rock is broken in order to harvest natural gas by drilling pipes vertically,and horizontally.Hydraulic fracturing, or fracking draws in the addition of more than a million gallons of water,sand,and chemicals being added below earth 's surface at a high pressure down a vertical,and horizontal pipeline.As the mixture travels down the pipe it breaks the Shale rock realising

    rocks to release gas inside. Some types of fracking are Hydraulic Fracking and Pneumatic Fracking. Hydraulic fracking happens when a liquid fluid such as water, oil and acid just to name a few is used to fracture rocks to release gas. The water brought in is mixed with sand and chemicals to create fracking fluid. Approximately 40,000 gallons of chemicals are used per fracturing (9). Pneumatic fracking has the same concept as hydraulic fracking except instead of using liquid base fluids it uses

    daily basis use, more and more states are starting to use hydraulic fracturing, at an alarming rate, to excavate these resources from beneath the shale rocks. Many experts, along with the public, believe that hydraulic fracturing has numerous environmental and health to both human and wildlife communities. Also, many believe that hydraulic fracturing possibly have moral and ethical implications that need to be address and fixed. With hydraulic fracturing being a very controversial topic between scientist

    verifies a strong positive linear relationship between the dimensionless jump height and the upstream Froude Number. These results imply that a more supercritical upstream flow in D1, will produce a larger downstream depth, D2, and thus a larger hydraulic jump. The results of the experiment confirm the following relationships a. D2/D1 > 1, the depth increases across the jump so that D2 > D1 b. F2 < 1, downstream flow must be subcritical c. F1 > 1, upstream flow must be supercritical It is observed
