HYDRODYNAMIC ANALYSIS OF WATER FLOW IN HILL PART OF THE CITY WATER SUPPLY NETWORK

Tema završnog rada je Hidrodinamička analiza strujanja vode u brdskom dijelu gradske vodovodne mreže. Obrađene su i opisane metode proračuna vodovodne mreže kao i osnovni zakoni mehanike fluida. Izrađen je model vodovodne mreže na osnovi zadanih parametara te simuliran njen rad pomoću računalnog programa za proračun stacionarnog strujanja EPANET 2. EPANET 2 je besplatan računalni program, dostupa na internetu (https://www.epa.gov/water-research/epanet). Nakon pokrenute simulacije analiziran je rad vodovodne mreže u vrijeme najveće i najmanje potrošnje vode od strane potrošača. Izračunate su vrijednosti tlakova u čvorovima i brzine u cijevima nakon što je na vodovodnu mrežu priključen hidrant koji u slučaju požara treba osigurati određeni protok.The topic of this paper is hydrodynamic analysis of the water flow in a water supply network. Methods of calculation of water supply network and basic fluid mechanics laws are described in this work. Model of a water supply network based on given parameters is created and the operation of network is simulated using EPANET 2 software – a software solution for computation of stationary flow calculation. EPANET 2 is a free software solution https://www.epa.gov/water-research/epanet). In the simulation the operation of network was tested in situations of maximum and minimum level of water consumption. The values of pressure in nodes and water velocity in pipes are calculated after the fire hydrant is connected in the network
