Finding pressure and speed of an incompressible liquid in the walls of permeable cylindrical pipes used in hydraulic circuits


Abstract in English

The extensive theoretical and empirical studies about the pressure and flux speed of an incompressible fluid have shown a number of varied hydraulic problems. This is as a result of insufficiency In analyzing and studying the variable forces and factors that are changing in both direction and magnitude. These forces appear when a fluid flows inside permeable cylindrical pipes. For this reason , we took into consideration all factors and losses affecting this case. Based on that, we obtained new mathematical equations to calculate both pressure and speed. Then we placed a solved arithmetic example. Through which we showed the tendency to reach constant streaming at all times studied after adding the new parameters.
