ANALYSIS AND CONSIDERATION OF THE PECULIARITIES OF THE STRUCTURE OF THE PRESSURIZED WATER SUPPLY SYSTEMS WHEN CALCULATING TRANSIENTS

The development of construction of pressure water supply systems in the Russian Federation,especially water supply systems intended for supplying significant amounts of water at very high pressures, requires cost-effective design solutions for these systems without unnecessary costs associated with an unreasonable increase in their strength performance. This, in turn, required the development of calculation methods and their implementation. Determining the initial flow distribution in ring pipe networks is a difficult task and it comes to solving a system of nonlinear equations, the number of which is equal to the number of closed loops (rings). The solution of rings connection is carried out by the method of successive approximations. Presentation of the ring network as a branched one simplifies setting its structure, but it is not the only possible one.
