Intro to Rocket Science Rockets are simply a flying objects that are given a well sufficient force and power to allow them to push their masses through the air. So rockets must be designed in a way to make their mission easier in terms of going and flying through the air. This can be accomplished by reducing the air resistance against the rocket, reducing the mass of the rocket, and many other factors that we will discuss through this report. So, a wide-short rocket will experience much more drag
Problems with filtration Although filtration is a very important process in the purification of the fermentation product obtained, there are certain problems associated with it too. 1. The process of filtration is very slow and time consuming. 2. The process is relatively difficult to be performed. 3. Labor requirement is high. 4. It may result in the contamination of the product with the filter aid and equipment. So to counter that problem, we use other methods for the purification of our product
Implants provide excellent support and stability for these dental appliances.Dental implants are artificial roots (usually titanium) that are surgically placed into the upper or lower jaw bone by the dental implantologist. Teeth which are attached to implants can be made very natural looking.Dental implants are strong and durable and will last many years. On occasion, they will
working process in which surface of the component is bombarded with tiny spherical media of diameter 0.05 mm to 1 mm called shots [7]. This will create small dimples on the surface. The main advantage of shot peening is its low cost and successful industrial application. The method also has some disadvantages such as the physical contact between the specimen surface and bombarding ball causes higher surface roughness to the component, which will be more severe in the case of soft materials and the
Measures and Suggestions 1) From the macro strategy should be to foster enterprise core competitive power as the center, establish the internationalization development strategy The core of the international strategy is to improve the international competitiveness of enterprises through innovation. Will enhance the enterprise the competitive ability, is not only the demands of the development of enterprise itself is also the need of improving national competitiveness under the economic globalization
1. INTRODUCTION F riction surfacing (FS) is a solid state coating process based on the plastic deformation of a metallic consumable rod. As depicted in a rotating rod is pressed against the substrate under an applied axial load. Frictional heat generates a viscoplastic boundary layer at the rod tip. The pressure and temperature conditions lead to an inter diffusion process resulting in a metallic bond between the plasticized material and the substrate. Heat conduction into the substrate enables this
OBJECTIVES AND LAYOUT OF THE THESIS; Objectives In the design of a metal forming process, the only factors that are known are the final product shape and the material with which it is to be made. The fundamental goal of process design in extrusion is to produce industrial parts with high quality, precise dimensions in a most economical way. In this endeavor process optimization is of immense importance. In this thesis Equal Channel Angular Pressing (ECAP) is modeled using finite element method and
Industrial Engineering, Faculty of Industrial Technology, Institute Technology of Medan, North Sumatra, Indonesia e-mail: herlinalbs@yahoo.com ABSTRACT Organic waste treatment has been developed widely with electrochemical methods, because has advantages of low cost and efficient, the exhaust gas does not contain toxic materials and hazardous waste and the temperature of secondary treatment process is relative low. Electrochemical oxidation of organic compounds using metal ion mediator is one alternative
