VI. INSTRUCTIONAL METHODOLOGY
  1. Assignments
    1. In-class activity: Participation in class discussions on aspects of applied fluid dynamics and approaches to solving fluid dynamics problems. For example, describe the variation of viscosity with temperature for both liquids and gases. Further examples are specifying the desired size of pipe or tubing for carrying a given flow rate of fluid at a specified velocity, computing the average velocity of flow in non-circular cross sections, and describe the general characteristics of fans, blowers, and compressors.
    2. In-class activity: Small group discussion and analysis of course content such as sizing flowmeters for pipe systems in buildings. Another example would be calculating the flow of compressed air through an HVAC application.
    3. In-class activity: In class computer exercises of fluid flow and psychometric chart processes
    4. Out-of-class assignment: Textbook readings covering topics in course content such as Bernoulli’s equation, Reynolds number, laminar flow, turbulent flow and energy losses due to friction
    5. Out-of-class assignment: Problem sets covering topics in course content that progressively develop skills in applied fluid mechanics problems. For example, determining how the Reynolds number is directly proportional to velocity & inversely proportional to viscosity. Another example would be calculating one, two and three dimensional steady flows of compressible and incompressible fluid in pipes and channels.
  2. Evaluation
    1. Exams/Quizzes/Tests: Bi-weekly quizzes to measure student's understanding of the concepts associated with the assigned topics. For example, calculate the minimum gage pressure required at a horizontal section of pipe discharging at atmospheric pressure. Or how to formulate a sensible heating or cooling process that involves the increase or decrease in the temperature of air without changing its humidity ratio.
    2. Exams/Quizzes/Tests: A written midterm exam to measure student's overall understanding of the concepts as well as analytical skills to solve applied fluid mechanics problems. For example, calculating the difference in pressure in an incompressible fluid across a a pipe reduction, or calculating minimum gauge pressure in the mains for an incompressible fluid to reach a proscribed height.
    3. Final Assessment: A comprehensive written final exam to measure student's overall understanding of the concepts as well as analytical skills to solve applied fluid mechanics problems. For example, calculate the Reynolds number when the laminar flow of a Newton ian fluid ceases to exist. Or calculate using the psychrometric chart, the dry bulb temperature and humidity ratio of mixed air from a service operation.
    4. Other: Problem sets are evaluated based on choosing the correct method of solution and the clarity and completeness of the problem presentation. The student must show all steps clearly and all formulas used.
