چکیده مقاله
The reason for the high pressure drop in water transmission is in relation to the leakage effect local leakage effect on high pressure decreasing in water pipeline This work led to improved standards for precession designs and installation techniques in the field of sub atmospheric transient pressures that can suck air into the water system due to repeated pipe breaks The numerical modeling and simulation which was defined by Method of Characteristics MOC provided a set of results Basically, the MOC approach transforms the water hammer partial differential equations into the ordinary differential equations along the characteristic lines Therefore, the computational model of fluid flow in nonlinear dynamic modeling in the water pipelines is examined In this work, based on the Geospatial Information Systems GIS , the Courant number was equal to 0 977 and in the field test, the pressure variation due to pressure surge was 1084 m/s in 0 005 sec The result of this research led to saving the amount of 200 liters per second of drinking water
