This webinar introduces the use of the ACGIH Velocity Pressure Method for calculating both dynamic and frictional losses in an industrial ventilation system. Using Bernoulli’s Principle for mutual conversion of velocity and static pressures, this method assigns loss factors for hoods, fittings and ductings which allow the static pressure loss to be determined by the appropriate loss factor and the velocity pressure. This allows versatility and ease when computing losses for changes in system airflow or design. The ACGIH Velocity Pressure Method for calculating frictional and dynamic static pressure losses in an industrial ventilation system is a consistent, accurate and easy to use method for both system design and evaluation.
