Leakage reduction in water supply system through the adjustment of its hydraulic efficiency

Research Article of American Journal of Engineering Research and Reviews Leakage reduction in water supply system through the adjustment of its hydraulic efficiency HAIDAR Hatem*, BARADA Ali**, HALAWANI Jalal*** * Associate Professor, Civil Engineering and Public Works Department, Lebanese University, Hadath Campus, Lebanon. ** PhD Student, Lebanese University, Ecole doctorale en science et Technonlogie, Hadath Campus, Baabda (Lebanon). Water & Environment Laboratory, Lebanese University, Tripoli, Lebanon, *** Professor, Director of Water & Environment Laboratory, Lebanese University, Tripoli, Lebanon The present paper provides a pilot example for water networks managers and operators intending to adjust the hydraulic condition of a pressurized water system to operations conditions with the objective to improve its efficiency. For this aim, a hydraulic modeling methodology has been applied and combined with site inspection, and field measurements. The selected water system operates under particular topographic and operational conditions and suffers from major problems making the system unable to deliver water with the designed volume to the regional reservoir. The system is studied under both steady and unsteady conditions. The study shows benefits of the proposed methodology in terms of water loss reduction which allows enhancing the hydraulic performance of the system. Consequently, the adjustment of a water system to fit with the real operations conditions has improved the hydraulic reliability and efficiency of the system. The novelty of this paper is two-fold. First, it gathers field measurements and hydraulic modeling. Second, it forecasts and measures the efficiency of proposed rehabilitation works by checking the performance of the water system. Therefore, the paper results can be useful to researchers in hydraulics who need an identification of relevant studies, as well as to practitioners interested in understanding the available methods, techniques and tools and their applicability level in real case studies.

Research on automated machine tool management model

Research Article of American Journal of Engineering Research and Reviews Research on automated machine tool management model Shuyu Mei*, Guozhu Chen, Liang Zhou College of Hydraulic & Environmental Engineering, China Three Gorges University, Yichang, 443002, China. With the development of science and technology, the advancement of industrialization, automated production has been widely used, and automated machine tools are also favored as modern equipment for automation management coordination. This paper considers that the automatic lathe may fail during the process of continuously processing a certain part. Therefore, establishing the best inspection interval and tool replacement strategy for model design makes the automatic machine tool management more mature, and then promotes the modern development of production equipment. Keywords: Automated management; Monte Carlo simulation, Industrial technology ...

A Laboratory-Based Experiment on the Efficacy of Graphitic Carbon Nitride Doped with Tungsten Chloride in the Degradation of Organic Dye Pollutant Rhodamine-b Dye from Wastewater

Research Article of American Journal of Engineering Research and Reviews A Laboratory-Based Experiment on the Efficacy of Graphitic Carbon Nitride Doped with Tungsten Chloride in the Degradation of Organic Dye Pollutant Rhodamine-b Dye from Wastewater Sheila Moraa Ngare1, Juliet Nzula1 and Donde Oscar Omondi2 1School of Environmental College of Tongji University, China. 2Egerton University, Department of environmental science, P. O. 536-20115, Egerton Kenya. Water is an essential commodity whose quantity and quality needs to be secured for easier accessibility at both the industrial, public and household levels. However, its availability in adequate quality and quantity have continued to decline worldwide. Indeed, rise in human population coupled with the climate change phenomena have greatly impacted on the quality of water resources through increased organic and inorganic pollution. Rhodamine B (RhB) dye is a common organic pollutant majorly in industrial wastewater and with numerous environmental and human health effects. The application of of graphitic carbon nitride (G-C3N4) in the purification of wastewater to enhance the removal of RhB in wastewater is a technology of interest to most most environmental quality regulators and agencies. The study was therefore aimed at investigating the performance of graphitic carbon nitride doped with tungsten chloride in the degradation of organic dye pollutant rhodamine B dye from wastewater. The study showed that the as-prepared hybrid photo catalyst exhibits an improved photo degradation performance because of its synergetic effect. Indeed, the photo excited electrons from g-C3N4 were able to efficiently separate and are injected to the conductive band of WO3. The optimum photo activity occurred at the optimum ratio of 0.25WO3/g- C3N4. There was also stability and efficiency within the hybrid catalyst within the photo degradation process. Indeed, the composite indicates a high activity for degradation of RhB under visible light irradiation. The presence of g-C3N4 proved to be ...

Design of Fault Simulation Software for Intake and Exhaust System of Marine Diesel Engine

Research Article of American Journal of Engineering Research and Reviews Design of Fault Simulation Software for Intake and Exhaust System of Marine Diesel Engine Wu Gang, Jiang Guohe, Li Baoyue,Chen Biwen, Wang Pengfei Merchant Marine College, Shanghai Maritime University, Shanghai, 201306, China Aiming at the problems of high operating cost, high training cost and large site requirement of traditional marine engine platform, the software of fault diagnosis system for marine diesel engine intake and exhaust system is developed by using Visual Studio 2012 platform. The relevant mathematical model is established by numerical method, and the conversion from mathematical model to code is realized to simulate the working status of marine intake and exhaust system in normal operation and failure. The results show that the simulation system runs well with low cost and small site requirement. It can accurately simulate the normal operation and fault state of the ship intake and exhaust system. It can be used for training work and improve the actual response ability of the trainers to the fault of the ship intake and exhaust system. Keywords: marine diesel engine; intake and exhaust system; fault simulation; mathematical model ...
