  1. Assignments
    1. In-class activity: Participation in discussions on engineering plumbing systems and approaches to solving plumbing system problems. For example, compute the total energy loss, elevation differences, or pressure differences for systems with any combination of pipes, minor losses, pumps, or reservoirs when the system carries a given flow rate.
    2. In-class activity: Case studies and design examples of the various plumbing systems studied in the course. For example, analyze and compare storm water drainage systems for various types of buildings based on the code regulations and design considerations.
    3. Out-of-class assignment: Readings to correspond with topics covered in class, such as fuel gas systems and domestic hot and cold water systems.
    4. Out-of-class assignment: Problem sets covering topics in course content that progressively develop skills in engineering plumbing problems. For example, compute the amount of flow that occurs in each branch of a two-branch parallel pipeline system and the head loss that occurs across the system when the total flow rate and the description of the system are known.
  2. Evaluation
    1. Other: The problem assignments will be evaluated for correctness of methodology and accuracy of the answer.
    2. Exams/Quizzes/Tests: Weekly problem sets that focus on design problems of plumbing systems.
    3. Exams/Quizzes/Tests: A written midterm exam to measure student's overall understanding of the concepts as well as analytical skills to solve engineering plumbing system problems. For example, list the parameters involved in pump selection and the types of information that must be specified for a given pump. Another example is to design an open channel to transmit a given rainwater discharge with uniform flow.
    4. Exams/Quizzes/Tests: A comprehensive written final exam to measure student's overall understanding of the concepts as well as analytical skills to solve engineering plumbing system problems. For example, use the force equation to compute the force exerted on bends in pipelines, pipe hangers, supports and seismic restraints.
