Hydraulic analysis of the water supply system for Novo Naselje (Poreč) with application of WaterCAD V8i and Urbano Hydra software package

Kroz ovaj diplomski rad prikazane su opće značajke i provedena je hidraulička analiza vodoopskrbnog sustava Novog Naselja kao dijela grada Poreča. Novo Naselje predstavlja stambeno-turistički dio grada u kojem su turisti smješteni u privatni smještaj i hotele, a industrije na ovom području nema. Dimenzioniranjem su zadovoljene sve potrebe potrošača za vodom kao i pripadajuće požarno opterećenje. U radu je prikazan plan iskolčenja od vodotornja do krajnjeg potrošača. Proračun se provodi za različite modele i varijante dotoka vode do vodne komore vodotornja. Model gravitacijskog dotoka vode do vodne komore vodotornja analiziran je kroz tri varijante različite dispozicije vodotornja, a model dotoka vode crpljenjem analizira se kroz dvije varijante, ovisno o poziciji crpne stanice. Kroz hidrauličku analizu varirani su materijali cijevi i broj istovremenih požara, a sve u svrhu dobivanja brzina, protoka i radnih tlakova duž mrežnog sustava cijevi. Materijali cijevi za koje su provedeni hidraulički proračuni su lijevano-željezne, PVC i čelične cijevi. Hidraulički proračun proveden je najprije u WaterCAD V8i računalnom programu, a zatim i u Urbano Hydra programu. Naposljetku se rezultati uspoređuju i validiraju, a pomoću računalnog programa Urbano Hydra dobiveni su uzdužni profili i karakteristični poprečni profili rovova.Through this master's thesis, general features of Novo Naselje, as part of the city od Poreč, are presented, and a hydraulic analysis of the water supply system is performed. Novo Naselje is a residential and tourist part of the city where tourists are accommodated in private accommodations and hotels, and there is no industry in this area of Poreč. All consumer water needs have been fulfilled as well as the associated fire load. A plan for stalking out from reservoir to the marginal consumer is shown. The calculation is carried out for different models and variants of water inflow towards reservoir of the water tower. The model of gravitational water inflow towards reservoir is analyzed through three variants of different disposition of the water tower, and the model of water inflow by pumping is analyzed through two variants, depending on the position of the pumping station. Through hydraulic analysis, the pipe materials and the number of simultaneous fires is varied, all for the purpose of obtaining velocities, flows and operating pressures along the pipe network system. The pipe materials for which the hydraulic calculations are performed are ductile iron, PVC and steel pipes. The hydraulic calculation is performed first in the WaterCAD V8i computer program (software package) and then in the Urbano Hydra software package. Finally, the results are compared and validated, and with the help of the computer program Urbano Hydra, longitudinal pipeline profiles and characteristic cross section profiles are obtained
