Hydraulic analysis of the water supply system with the application of the WaterCad v8i and Urbano Hydra program packages

Unutar ovog diplomskog rada provedena je analiza hidrauličkog proračuna za Grad Pulu. Ovaj proračun je proveden primjenom programa WaterCAD v8i i programa Urbano Hydra. Hidrauličko opterećenje ovog rada sačinjavalo je stanovništvo s turistima, dva hotela, kamp, odmaralište i dvije industrije. Prilikom dimenzioniranja su zadovoljene sve potrebe potrošača za vodom. Osim potrošača proračunato je i požarno opterećenje za požare unutar zone stanovništva i industrijske zone. Sustav je proračunat za dva modela dotoka vode u vodotoranj. Modeli dotoka vode u vodotoranj su gravitacijski model dotoka i dotok vode uz pomoć crpljenja. Kapacitet vodotornja je dobiven zbrajanjem operativne, protupožarne i sigurnosne rezerve. Cjevovod je proveden po prometnicama. Odabrane su lijevano željezne cijevi. Pomoću WaterCAD-a proračunate su promjene protoka i brzine vode u cijevima. Program Urbano Hydra je korišten za proračun promjene protoka i brzine vode u cijevima i izradu uzdužnih profila i poprečnih presjeka. Scenariji koji su provedeni su: bez požara, s jednim požarom, s dva požara i s dva požara i požarom u industriji. Promjena protoka i brzina koje su dobiveni unutar ovih scenarija uspoređena su unutar dva programa.This graduate thesis is about analysis of hydraulic calculation for city of Pula. Calculation was made in WaterCAD v8i and Urbano Hydra. Hydraulic calculation is concluding population and tourist, two hotels, camp and two industries. Design of water supplying system accommodate all water needs. This system is designed for protection in the case of fire, for the fire in city and fire in industries. Water supply system was calculated by two models for inflow water in water tower. Models of inflow water in water tower are: gravitational flow od water and flow in water tank using a pumps. Capacity of water tower was calculated as a sum of operational storage, fire suppression storage and standby storage. Pipeline was routed along the roads. Materials of pipeline is ductile iron. Oscillations of water flow and velocity, was calculated in WaterCAD V8i computer program. Urbano Hydra computer program was calculating oscillations of water flow, velocity and draft of longitudinal profile and cross section. In this thesis scenarios are: scenario without fire, scenario with one fire, two fires and two fires and one fire in industries. Oscillations of water flow and velocity was compared in this two computer software’s
