Here, for the first time, is an authoritative technical reference book covering all aspects of state-of-the-art design of ventilation systems for contaminant control for a wide variety of manufacturing and processing industries. The author has played a key role in the development of the subject and this book is based on his extensive consulting experience in the practical engineering design of contaminant control systems world-wide, as well as his personal research work. The material is organized specifically for ease of understanding and contains all the technical information needed to develop cost-effective solutions for any type of contaminant in the workplace environment. A unique feature is the development of recommended subject classifications for the ventilation field. For each type of ventilation system, the fundamental design equations are developed from theoretical principles, and numerous examples are given of the practical application of these design equations to solving industrial ventilation problems.
