Hydrodynamic analysis of a flow in water supply city network

The basis of the modelling and calculating of water supply network is given in this work The theoretical basis of hydraulic complex pipelines function is described, which is base for the modelling process of pipe networks and so for modelling the gravitational water supply city network. The computer program EPANET 2 is used for the calculation of the values of pressure and velocity in the pipe network for two cases of the pipe network operation: normal, usual operation and operation during the conflagration, when hydrant supplies the water with the volume flow rate of 5 l/s. The analysis of the results is performed and it is concluded that the pipe network allows the normal supply of the city, even in the case of conflagration when the hydrant operates. The city water supply network is graphically shown, with the values of pressure in the nodes, and velocity in the pipes during its operation.
