Open surface tanks are used in many industrial processes and are quite common for processes such as pickling, etching, and plating. If proper ventilation is not provided, workers in the vicinity of these processes could experience irritation due to the toxic fumes diffused from the materials in the open surface tanks. For this reason, proper design of push-pull hoods is required to ensure the health and safety of workers as well as to maintain the integrity of the associated products. In addition, it is very desirable, from the point of energy conservation, to determine an optimum and efficient design of push-pull hoods which can exhaust all contaminants with a minimum quantity of flow volume. This type of design will reduce heat lossl gain to the space as well as minimize the fan power required.
In Part I of this paper, the following basic points concerning the push-pull hoods were investigated both theoretically and experimentally.
