Hence, this research was conducted to carry out the hydraulic modeling of the Aksum town water distribution system which is located in the Central Tigray region of Ethiopia. The objectives of this research were to evaluate the hydraulic performance of the water supply distribution system by assessing the situation of the existing water supply distribution system. Water GEMS V8i software was used as a tool to model the water distribution system. The model can be used to identify the high pressure and low pressure in the junctions and the magnitude of velocity through pipes was used as a base to evaluate the hydraulic performance. Modeling results showed a violation of maximum and minimum pressure and low-velocity requirements. High pressures in the system occurred both during low demand and peak demand have to be identified. The simulation result of the existing system about 38.6% of the junctions was failed to satisfy the allowable pressure and the velocity of about 34.9% was failed out of range during the peak consumption hour. The model performance measures were checked based on the coefficient of determination. In general, it was concluded that the existing water distribution network systems of Aksum town categorized under satisfactory hydraulic performance situation and were not supply adequate water to various demand categories of the town. In the modified system, the network runs hydraulic parameters are radically improved using the Pressure Reducer Valve added in the system to reduce high-pressure impacts on water distribution system. The results of the simulation show that the hydraulic simulation about 43.4% of pipes of diameter from the total water distribution system pipe diameters needed to be upgraded.","PeriodicalId":52256,"journal":{"name":"Tumu yu Huanjing Gongcheng Xuebao/Journal of Civil and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73821172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, the nanoparticles are annealed at 400°C and the samples are characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, photoluminescence spectroscopy (PL) and photo catalytic studies. XRD analysis deciphered the polycrystalline hexagonal of the samples and the crystallites sizes are observed to be 18 nm and 42 nm for the pure and Mn doped ZnO particles, respectively. FE-SEM studies demonstrate that the crystallites are spherical in shape with agglomeration. PL studies reveal the emission bands at 490 nm for pure ZnO and 530 nm for Mn doped ZnO. The photocatalytic studies determine the photocatalytic performance of pure ZnO NPs and Mn doped ZnO NPs under the UV light irradiation (365 nm and 125 W) in which, the pure ZnO degrades MB dye more efficiently than Mn doped ZnO.","PeriodicalId":52256,"journal":{"name":"Tumu yu Huanjing Gongcheng Xuebao/Journal of Civil and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82129598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In India, a large portion of the Thermal force plants embrace wet technique for debris removal. Lake debris is gathered from Thermal force plant at the base, in that it contains critical measure of generally coarser particles (crossing from 150 microns to 2.36 mm). Lake debris usage assists with diminishing the utilization of normal assets. Additionally it is help to take care of the issue of removal of Pond debris since it contains enormous measure of substance mixes, for example, SiO2, Al2O3 and so on. These synthetic mixes (SiO2, Al2O3) are assumes a significant job in hydration response and assists with delivering bond between two nearby particles. Utilization of Pond Ash in concrete is a significant eco productivity drive. It is important to locate the specific appropriate rates of lake debris so it is chosen to use in differing rate as 0%, 5% 10%, 15%, 20%, 25%, 30%. Also, to check the properties of new concrete and solidified cement, for example, droop and compressive quality, rigidity, flexural quality individually. Likewise solid assumes a significant job in long life time of structure so it is additionally critical to check impact on strength by utilizing sulfate assault, chloride particle entrance, drying shrinkage. Study shows the essential properties of Pond ash. It likewise contrasts these properties and characteristic sand. Fractional substitution doesn't bring on any unfavorable impact on properties of new concrete. The outcome shows that solid invigorating great with fractional substitution of fine total.
