Water Environment Research, Vol. 76, No. 3 (May - Jun., 2004), pp. 231-237 (7 pages) An adequate supply of dissolved oxygen is important in natural rivers and in some water treatment processes. The ...

Effects of split injection, with a relatively short time interval between the two sprays, on the spray development process, and the air entrainment into the spray, were investigated by using laser ...

As the fire service has evolved, so have our tools to deliver the primary extinguishing agent, water, to the seat of the fire. What was once delivered with a smooth-bore nozzle can now be applied in ...

AIR is often entrained naturally by flowing water—for example, in the plunging waters of mountain streams, waterfalls, bores, breakers, hydraulic jumps and subterranean siphons—and, in these and ...

Understanding the fundamentals of hose stream mechanics is vital to the success of fire suppression operations on the fireground. This includes understanding: when and how to utilize air entrainment ...

The additive conditions of this table help the user/specifier determine where the concrete is to be placed in relationship to the exposure of the two primary conditions, freeze-thaw cycles and ...

THIS communication reports an investigation of the conditions for air entrainment when a water jet impinges normally on an air–water surface. The calculated critical entrainment velocity of the jet is ...

Although concrete is commonly perceived as a dry and dense substance, it is actually an inherently porous material that more closely resembles a hard sponge. Within concrete’s matrix are microscopic ...
