Page Count: 78: Abstract: A new design criteria for local exhaust systems for open surface tanks is developed taking into account higher gassing rates due to increased plating current densities, use of surface control agents such as plastic balls, push-pull …
WebDec 1, 1996 · Existing design guidelines for push-pull systems vary greatly, although most agree that the system can yield air savings of up to 50%. Starting from an understanding of the nature of the fluid flow this paper develops guidelines for the important parameters of the system and compares these to the recommendations given in earlier work. WebIn the case of push-pull ventilation the conditions are a wall jet with a decaying maximum velocity and very low velocities outside the jet area. 3 . By using the local maximum wall jet velocity as the free stream velocity and by substituting equation (2) into equation (6) and integrating the equation over the length of the water surface ...
