Condensed air in the water stream causes serious problems such as head drop, localized pressure increases high noise generation, shaking in the pipes, as well as the loss of pumps in the system will be transmitted. To remove air from the system, air valves should be used. In this research, the hydraulic properties of air flow contained in the water pipes is studied, then a program is developed for providing the optimal solution regarding the size and position of the valves in the right place by using MATLAB software. The general method is to examine all the tube parts at the failure location by the direct search algorithm and find the lowest gradient and calculate the initial discharge rate of the line as following: First, the minimum amount of air intake in the water pipeline will occur. Second, the air outlet speed of the system will be optimal. To enhance the applicability of the proposed method, the model was developed in the GUI environment. Finally, for the verification and evaluation of the results, an identical model of water pipeline using Valmatic software and the present developed software has been analyzed.
