SummaryFrom drinking fountains at playgrounds, water systems in homes, and working bathrooms at schools to hydraulic bridges and levee systems, fluid mechanics are an essential part of daily life. Fluid mechanics, the study of how forces are applied to fluids, is outlined in this unit as a sequence of two lessons and three corresponding activities. The first lesson provides a basic introduction to Pascal's law, Archimedes' principle and Bernoulli's principle and presents fundamental definitions, equations and problems to solve with students, as well as engineering applications. The second lesson provides a basic introduction to above-ground storage tanks, their pervasive use in the Houston Ship Channel, and different types of storage tank failure in major storms and hurricanes. The unit concludes with students applying what they have learned to determine the stability of individual above-ground storage tanks given specific storm conditions so they can analyze their stability in changing storm conditions, followed by a project to design their own storage tanks to address the issues of uplift, displacement and buckling in storm conditions.
Physics and fluid mechanics are integral parts of engineering, and both are typically presented as required courses at most universities for most engineering majors. Engineers apply Pascal's law, Archimedes' principle and Bernoulli's principle to design and construct various floating vessels, submersibles, airplanes, automobiles, pipelines and transport systems, hydraulic structures and even petrochemical storage tanks. Ocean and marine engineers study the offshore environment to design oil rigs and production platforms as well as floating vessels and subsea pipeline systems needed in the oil production process. Other engineers design different types of submersibles and remotely operated vehicles used to explore deep-water environments. Still other engineers apply these scientific concepts to become specialists in hydraulics—the use of liquid power to do work—and they design heavy machinery, water distribution systems, sewage networks, storm water management systems, bridges, dams, channels, canals and levees.
Overview of topics by lesson: 1) Archimedes' principle, Pascal's law, Bernoulli's principle, 2) the concepts covered in the first lesson applied to the use and failure of above-ground storage tanks in the Houston Ship Channel.
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,
technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.
