The first part of the course deals with the basic principles of ventilation system design and quality and quantity control aspects of air. Selection of economic size of airways and auxiliary ventilation systems are studied. The second part deals with the theory and applications of ventilation fans, instrumentation, survey techniques and conditioning of air flows. The capture velocities of dust and balanced dust and fume control system design and efficiency of air filtering systems are examined. PREREQ: ENGR 2036 and ENGR 2097. (lec 3, lab 1.5) cr 3.
