بيّنت الدراسات النظرية و العملية الواسعة لضغط و سرعة التدفق لسائل غير قابل للانضغاط، ظهور العديد من المشاكل الهيدروليكية المتنوعة، نتيجة لعدم كفاية الدراسة و التحليل للقوى و العوامل المتغيرة قيمةً و اتجاهاً، و التي تظهر عند جريان سائل في الانابيب الاسطوانية القابلة للنفاذية، لهذا السبب قمنا بمراعاة جميع العوامل و الضياعات المؤثرة في هذه الحالة، و بناءاً عليه، حصلنا على علاقات رياضية جديدة لحساب كل من الضغط و السرعة ثم وضعنا مثالا حسابياً محمولا ، حيث بينا من خلاله الميل لاستقرار عملية التدفق في جميع الأزمنة المدروسة و ذلك بعد إضافة البارامترات الجديدة.
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.

Hydraulic system was designed and installed to estimate values of Bulk modulus within the range of
pressure between 20 bar to 230 bar and temperature between 5° C to 90° C; these limits are the widest
range in which it operates hydraulic systems .
In this research the mineral oil (SAE 46) is heated
(indirectly method) and then pressed into a pipe with large thickness compared with internal diameter so
as to ensure that the results will not be affected by the elasticity of the pipe material. The results for the
characteristics‚the pressure and temperature have been indicated by gages installed on the line of
hydraulic circuit while taking readings compressibility through indicator tube. It was concluded that the
temperature of mineral oil have an effective impact on the Bulk modulus values even at lower
temperatures lower than 50° C and the sloop (of the relation curve between Bulk modulus and pressure)
is reduced with temperature increase. it was also estimated that values of Bulk modulus are volatileat
pressures less than 100 bar with increasing temperatures for this mineral oil.
This paper presents an experimental investigation of the flow pattern and wall pressure due to the change of the opening discharge diameter in cylindrical silos. The experiments were performed on a
metal silo prototype using corn as a granular mater
ial. The silo prototype used in the study was built of a metallic cylinder, which can be opened longitudinally allowing the observation of the flow pattern
through a plexi-glass wall, and the wall pressure distribution was measured using a special granular pressure transducer. The present study revealed unexpected results to what might be expected through
current theoretical knowledge.
In this research, technical fabrics are used as blankets which prevent soil surface erosion and promote
seed germination as way to mitigation of desertification .
Five different types of fabrics are prepared of natural fiber: coir, hemp, jute, trea
ted cotton and raw
cotton, then three hydraulic properties for prepared fabrics are tested: swell, water absorption, water
vapour permeability.
It is found that all types of prepared fabrics are suitable to combat desertification whereas they have a
high water absorption and they reduce water evaporation, the fabrics of jute and treated cotton have the
highest water absorption and the fabrics of hemp and raw cotton have the lowest water vapour
permeability.
In this research, the optimum rate of burnishing force for
burnishing samples of Al-6061 was found, in order to have the
best finish of the surface .
Different tests were carried out on samples of Al-6061 by
application different values of burnis
hing force without changing
the other parameters of the ball burnishing operation .
The experiences were carried out by using ball burnishing tool
and CNC milling machine with three-axis .
The spread of the modern data transfer techniques, in modern industrial and agricultural applications, and service areas, leads to the need to transfer this data effectively and flexibly, within installations parts.
This research aims to apply the h
ybrid mechanism, based on the use of ZigBee technology, and CAN Bus together to ensure the best performance, in accordance with the performance indicators required by the networks of these facilities, in near-real time operation. The study attempts to compare this mechanism with other mechanisms proposed in similar research.
The proposed solution supports the use of a hybrid data transfer networks, based on the internetworking of CAN Bus networks, using a backbone based on wireless ZigBee technology. This solution proposes an appropriate structure for gateways between the hybrid parts of the network. The research has concluded that the proposed mechanism preference, compared with the proposed mechanisms in similar research, according to the standards of performance indicators, is suitable for this kind of networks, as it allows us to recommend the use of this mechanism in the service and industrial applications. The NS2 network simulator is used to evaluate and compare the obtained results.
