The profiles are similar to those for the round hood but are more elongated.
Contaminants of high toxicity.Makeup air supplied by general ventilation to replace exhausted air can dilute contaminants that are not captured by the hood.Ashrae Technical Committees in each subject area have reviewed all chapters and revised them as needed for current technology and design accompanying ashrae CD-ROM contains all the volume's chapters in both I-P and SI units.Some types of energy recovery equipment handbook may allow considerable cross-contamination (e.g., heat wheels) from the exhaust applications into the supply airstream, whereas other types (e.g., runaround coils) do not.Negative building pressure allows applications air to infiltrate applications through open doors, window cracks, and backfeed through combustion equipment vents. Evaporation from tanks, degreasing, plating, released at low velocity into moderately still air.
Of water can maroto cause drafts and might cause backdrafts in combustion vents, thereby creating a potential health hazard.
These factors engineering can significantly reduce the capturing effectiveness of drivers local exhausts and should be accounted for in exhaust system design.

Local exhaust ventilation optimizes ventilation exhaust airflow, airflow, thus ebooks optimizing system operating costs.
Bibliography Bastress,.,.Velocity distributions for specific hoods must be known or determined.An experimental study of the pressure losses in converging flow fittings used in exhaust systems.The second component of a local exhaust ventilation system is the duct through which contaminated air is transported from the hood(s).System design should incorporate the maximum pressure drop of the cleaner, or hood flow rates will be lower than designed during most of the duty cycle.Enclosing hoods provide more effective and economical contaminant control because their exhaust rates and the effects of r oom air currents are minimal compared to mavrk those for nonenclosing hoods.Design velocities can be higher than minimum transport velocities but should never be significantly lower.Using outside air minimizes replacement air requirements.As a result, the hoods can fail to control the contaminant adequately, exposing workers to potentially hazardous contaminant concentrations.Container filling, low-speed conveyor transfers, drawing welding 100 to 200, probook active generation into zone of rapid air motion.Small hood; local control only.7 Entry Losses for Typical Hoods Fig.
