INDUSTRIAL   VENTILATION

  CIVE  4670 / 5670

 

Objectives: At the conclusion of the course you should be able to apply the knowledge of the mathematics, science and engineering to identify and to solve industrial ventilation problems. The course will help you to design simple industrial ventilation systems using a spreadsheet software available in a typical engineering office. You may be required to present project report in the class in order to improve communication skills.

Course Description: Industrial ventilation as related to the need of industrial hygiene engineer, including principles of air flow, natural ventilation, dilution ventilation, fans, collectors, testing instruments and construction guidelines for local exhaust systems and design of industrial ventilation systems.
