In general, internal vibrations within the pipelines caused by fluids being passing through a pipeline system can cause. These pipeline system can damage by the sudden amplified vibrations that were not considered at the design of the system, and flow induced vibrations resonate with the pipes natural frequency. Therefore, it is important to predict and identify the pipeline system vibrations during its lifetime. In this study by using MATLAB code as a CFD solver, it studied the forced and free vibrations caused by fluid flows at Reynolds number ranged as 0 < Re < 2500 for laminar flow and ranged as 104 < Re < 105 for turbulent flow. The working fluid has chosen as of (Al2O3, TiO2, SiO2 and water) with different nanoparticle volume fraction of (0 to 2% vol.). These fluids flow in simply supported pipe with different lengths and diameters. The results presented the effect of pipe and fluid parameter upon the fluid critical velocity and fundamental natural frequencies. The results showed that the pipe natural frequency increased with increasing with decreasing the pipe length and diameter. In addition, it showed that the pipe natural frequency decreased when using the different nanoparticle depressed in the water and with increasing the volume fraction.

Engineering and Technology Journal
In this work, a pilot unit using side-stream MBR configuration was operated in BioFlow mode (i.e. no back pulse) and BioPulse mode (with intermittent back pulses) to treat municipal wastewater with relatively low MLSS. The results showed that the trans-membrane pressure (TMP) was less in the case of BioPulse over the whole period of system operation compared to that of BioFlow mode. However, the energy consumption per unit volume of permeated water is slightly higher in the case of BioFlow mode (3.4 kW.hr/m3) than that in the case of BioPulse mode (3.2 kW.hr/m3). Therefore, operation in BioPulse is preferable due …

An Overview On Most Effective Dras In Crude Oil Pipelines, Raheeq Ibrahim, Manal Odah, Dhoha Shafeeq
Engineering and Technology Journal
The flow of crude oil in pipelines suffers from a problem of fluid flow pressure drop and high-energy consumption for pumping especially in low temperatures environment. Flow can be enhanced using viscosity either reduction or drag reduction techniques. Drag reduction is considered as the most effective and most applicable method. The technique contributes in reducing the frictional energy losses during the flow by addition of little doses of materials knowing as drag-reducing agents. The present work focuses on more recent and most applicable drag-reducing agents used in crude oil flow enhancement via pipelines.

Gypseous soil characteristics were studied types many researchers, but the bearing capacity of sandy gypseous soil with different preparing of the soil models were tested in dry condition under static and cyclic loads in this study, three types of gypseous soils are prepared (artificial, gypsified and natural gypseous soils). The laboratory tests were needed to evaluate geotechnical soil properties. The main objective of this study is testing of the soil models in dry condition for measuring earth pressures with displacements of the soil models under monotonic and repeated loads within relatively large manufactured physical model. The results found that the …

Nowadays Internet of Things (IoT) is growing to be a serious factor in numerous areas of our daily life style. Internet of Things brings different opportunities of intelligence to important aspects such as health, payments, energy management, industrial sectors, transportation and also many other specialties. It is important to notice that the interaction between these two part the embedded equipment and Cloud based web services is such a common or prevalent scenario of Internet of Things deployment. When it comes to the security point of view, jointly users (consumer) and smart devices need to reassure and establish a secure and …

In this study, Al-Diwaniyah River within Al-Diwaniyah Governorate was monitored for a set of chemical, physical,and bacteriological parameters for the assessment of water quality during January to July 2018. Water quality maps for this river were plotted torepresent the change in each parameter during the study period using GIS program. Three sampling stations along the river and eighteen parameters were selected: air temperature, water temperature, turbidity, pH value, electrical conductivity (EC), biochemical oxygen demand (BOD), dissolved oxygen (DO), alkalinity, chloride, Sulfate, total suspended solids (TSS), total dissolved solids (TDS), calcium, magnesium, total hardness, lead, total coliform,and Escherichia coli bacteria. The …
