Learning Objectives

  • Develop an ability to solve basic and fundamental problems such as the force distribution on a dam, pump size required to move water though a practical pipe network, engine power required to keep a car moving forward at a specified velocity, and wind speed required to test a model car in a wind tunnel.
  • Expand your ability to apply mathematics and physics to engineering problems involving fluid mechanics. This is strongly emphasized through lectures and homework.
  • Expand your ability to conduct experiments, as well as to analyze and interpret data through performing the planned laboratories and writing the lab reports. Analysis of experimental error is emphasized.
  • Enhance your ability to identify, formulate, and solve engineering problems through your participation in the problem-based team project this semester. This problem involves the design of scaled model experiments of a complex full-scale engineering device.
  • Enhance your skills related to teamwork through the semester project which is performed in groups of 3 to 5 students.
  • Enhance your ability to learn new material on your own through the problem-based learning aspects of the semester project. In this work, you will learn about an area of fluid mechanics by library research with your group.
  • Enhance your ability to work with modern engineering measurement equipment through the performance of 4 laboratory assignments.
