Subject Title
Pipe Systems Design

Subject Description
Students study the design, components and operating characteristics of hydronic systems in buildings.  Emphasis is on determining piping system load capacity and ensuring pipe system efficiency and cost control while maintaining the desired heating and cooling for building inhabitants.

Credit Status
One elective credit toward the Building Environmental Systems (BES) Operator Class I Certificate

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Discuss the basic principles of pump operations as part of the hydronic system design.
2. Describe the use of pump curves in pump selection.
3. Apply the basic criteria in parallel pump curves and series pump curves and selection.
4. Compare pipe sizing techniques for different piping materials.
5. Evaluate resistance in closed and open loop piping systems.
6. Describe steam piping sizing and design principles.
7. Discuss the need for balancing hydronic systems and basic techniques used in systems balancing.
8. Calculate the hydronic load calculation for heating and cooling.
9. Assess the impact of pipe systems design on the achievement of energy efficiency

Class II designation recommended

Topic Outline

  • The types of pumps and pump laws with respect to speed of motor, flow rate, pressure and frictional loss, and power requirement
  • Single pump curves and system characteristics including impeller size, efficiency, motor drive capacity and hydrostatic head pressure
  • Parallel pump connections, series pump connections and their resultant characteristics
  • Use of charts to evaluate resistance pipe size, flow rate and capacity
  • Introduction to the essential difference between steam and water flows in pipes leading to the need for different considerations between the two systems
  • The undesirable results of an unbalanced system, the need to balance flows in a system, the theoretical approaches to system balancing and the use of devices for such purposes
  • The relationship between heating and cooling loads and requirements to satisfy these loads
  • Load calculation and equipment providing such services
  • Total systems evaluations considering all the components in the system and their functions

Modes of Evaluation
Since this is a professional credit subject, marking standards reinforce professional practice by demanding legible, tidy work. Written projects should be well organized and grammatically correct, with proper spelling and punctuation. Late projects are penalized. Please obtain standards, dates and additional information from your instructor.

While attendance is not a formal part of the evaluation process, absenteeism will almost guarantee your inability to achieve a satisfactory grade, as there is no formal provision for make-up tests or projects you may miss.

To attain a passing grade for the subject, a student must complete and obtain a passing grade on all combined projects and tests during the term.  For further information on evaluation and academic standing, see a copy of the Academic Policy. They are available at Seneca Registration offices.

Grading is based on the following marking scheme:

Project                 25%
Midterm              35%
Final                      40%

Correspondence and Online
Project 1              30%
Project 2              30%
Final                      40%
