Abstract

One of the ways studied in different countries of the world, especially the United States, to lessen the problems facing in ground transportation of goods, is the hydraulic transportation of agricultural and industrial products. Certain discoveries since 1950’s led the scientists to gradually realize that if chemical substances are present in a liquid in two different phases in terms of chemical compounds so that they cannot be merged, they can be transferred together through a pipe from one place to another. Later, vast research was conducted on this subject, and in recent years the related research has been mainly carried out at the Missouri State University in the United States, with the result that by certain floating containers made through a special method, it is possible to transfer agricultural and industrial products through pipes. In the following, a summary of research and modeled examples of the above-mentioned system, carried out by two Iranian and Chinese researchers, Nikdeh and Li in the Missouri State University is presented.
In the second section of this paper, transfer of materials without energy is examined.
