SHM 108 - Advanced Mechanical Drawing
1 Lecture Hours 4 Lab Hours
Prerequisites: SHM 104
This is a course in advanced mechanical drawing and HVAC applications. Students will get instruction on oblique, isometric and perspective drawings. These techniques will be practiced extensively in creating drawings which would be used in design and fabrication of HVAC systems.
Upon successful completion of the course, the student will:
- Plan a drawing project given an object or system to draw and limited space parameters.
- Project section views of round objects cut off plane.
- Draw a given product or series of products in oblique, isometric or section view.
- Correctly dimension and detail an isometric or oblique drawing.
- Explain the difference between pressure dependent and independent VAV control boxes.
- Choose an appropriate type of VAV box given a blueprint with floor layout and human occupancy.
- Predict problems that could occur within a given system of control boxes and engineer’s drawing.
- Choose an appropriate model of control box given CFM requirements and manufacturer submittals.
- Choose an appropriate duct size given CFM and velocity data.
- Define friction loss.
- Define aspect ratio.
- Explain laminar airflow in terms related to aspect ratio.
- Discuss differences in calculation of duct size verses equal friction duct sizing.
