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.

Miller - Plasma Cutting Guide.pdf
Taken from Plasma Advantages: Plasma provides numerous advantages over other cutting processes. While there are many common methods of cutting metal, the plasma process offers the following advantages:
Cuts any type of electrically conductive metals including aluminum, copper, brass and stainless steel
Cuts faster — up to 130 in. per minute on 1/4 in. steel
Does not require a pre-heat cycle which saves time and is more convenient
Produces a small and more precise kerf (width of the cut)—great when precision matters
Has a smaller heat affected zone which prevents the area around the cut from warping and minimizes paint damage
Provides gouging and piercing capabilities
Sawing or chopping can take a long time and will typically leave a rough edge — plasma cutting is fast, clean, and leaves a nice straight edge. It is also a less expensive and more convenient method for cutting than many other processes because compressed air is typically available in most applications via shop or portable compressors.
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.
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.
