520    Detailed coverage of both theoretical and practical 
       aspects of industrial ventilation systems--newly updated 
       in this Second Edition  Designed to be used with the ACGIH
       Industrial Ventilation manual, Ventilation for Control of 
       the Work Environment explains the rationale of the 
       material contained in the manual while demonstrating both 
       the theoretical and practical aspects of the subject. The 
       design of local exhaust ventilation systems is illustrated
       by examples taken from the authors' industrial experience.
       In addition, end-of-chapter problem sets are now presented
       to reinforce the content of appropriate chapters. Both 
       English and metric units are used in this new edition, and
       new ventilation practices and research advances are noted 
       throughout this major revision.   Topics covered include: 
       Overview of industrial exhaust ventilation and its impact 
       Fluid mechanics Methods and instrumentation for measuring 
       airflow Hood design, selection, and performance The design
       of local exhaust ventilation systems Fan design and 
       performance Air-cleaning devices Computational fluid 
       dynamics Dealing with the reentry of exhausted air
