• Description:
  This report contains lecture outlines on both the principles of ventilation and ventilation measurements. The principles of ventilation lectures cover: the purpose of ventilation to control airborne contaminants; thermal ventilation effects from hot operations; local exhaust systems; characteristics of various types of hoods; principles of air flow; pressure requirements in a ductwork system; air flow through hoods; air flow in ducts; use of fans to effect air movement; various types of fans and dust collectors; and common problems encountered in ventilating systems. The ventilation measurement lectures cover: the reasons for taking ventilation measurements; types of system measured; types of measurements taken; instruments used to measure velocity; factors affecting choice of air meters; pitot tubes; Alnor velometer swinging vane anemometer; Alnor thermoanemometer; rotating vane anemometer; Dwyer air meter; smoke tubes; measurement and character of flow at hood openings; methods for determining air flow into hood openings; measurements of specific types of hoods; measurement of general ventilation; criteria and recommended rates for hoods, open surface tanks and welding; and trouble shooting an exhaust system.
