Hydrodinamics of Pumps.pdf
Taken from Abstract: The subject of this monograph is the fluid dynamics of liquid turbomachines, particularly pumps. Rather than attempt a general treatise on turbomachines, we shall focus attention on those special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to these special problems, and cause a significantly different set of concerns than would occur in, say, a gas turbine. These are the potential for cavitation and the high density of liquids that enhances the possibility of damaging unsteady flows and forces.
Finite Element Modeling of 3D Turning of Titanium.pdf
Titanium (Ti) and its alloys are lightweight, corrosion resistant, and high temperature materials. Titanium has the highest strength-weight ratio of all commonly used metals up to 550 C. Titanium is the ninth most abundant element and the fourth most abundant metal in earth’s crust. However, the extraction and processing cost to produce raw Ti material is high due to its high free energy for reduction of oxide. The high cost has limited Ti to the military, aerospace, racing, medical, and other, applications in which the material cost is not a key factor.
LAYMAN’s Guidebook on how Develop a Small Hydro Site.pdf
Taken from Definition of small hydropower: There is no consensus in EU member states on the definition of small hydropower: Some countries like Portugal, Spain, Ireland, and now, Greece and Belgium, accept 10 MW as the upper limit for installed capacity. In Italy the limit is fixed at 3 MW (plants with larger installed power should sell their electricity at lower prices); in France the limit was established at 8 MW and UK favour 5 MW. Hereunder will be considered as small any scheme with an installed capacity of 10 MW or less. This figure is adopted by five member states, ESHA, the European Commission and UNIPEDE (International Union of Producers and Distributors of Electricity).
What is a Mechanical Engineer?.pdf
Mechanical engineering is a profession requiring specific skills. These skills are acquired through education, training and experience. Throughout high school, students must enroll in certain courses as preparation for acceptance into engineering programs at a college or university. A solid foundation in mathematics, science and the language arts is critical.
Strong mathematics preparation includes algebra, geometry, trigonometry and calculus. Chemistry, biology and physics form the basic science foundation. Ability in oral and written communications is important to success in mechanical engineering studies, and courses in mechanical or computer-aided drafting/drawing and other technology-related subjects can help students begin to understand the important practicalities of technological projects.
Students can enhance their studies and enrich the overall learning experience by entering science and technology fairs and design competitions, and by joining clubs or career groups devoted to engineering and science. Some clubs sponsor day trips and similar excursions to companies, laboratories and industrial facilities, where students can meet engineers in actual work environments.
nanoEngine Hardware Reference Manual.pdf
Taken from nanoEngine Overview: Bright Star Engineering’s nanoEngine single board computer provides an unprecedented level of power and integration in a 1.4″ by 2.4″ module. Utilizing the Intel SA1110 StrongARM processor, the nanoEngine is able to provide desktop system class-performance yet consumes well under 2 watts of power.
