Due to fluid movement in fuel pipes and tanks, the electric charge will emerge in the fluid and its common surface with the pipes. As these charges become discharged the tanks and pipes are threatened; because the discharge energy becomes more than the lowest required energy of the fuel explosion and can lead to the fuel flaming and the explosion of tanks and tubes. In this article, the effect of the conductive and insulator pipes, the fluid velocity, and the pipe radius in the production of electric charge have been analyzed and studied. Always, in the calm fluid current, the produced electric charge is lesser than the turbulent fluid current counterparts. With more velocity of the fluid, the turbulent will become more occurred The results show that in the state of calm flow, the generated electric current is almost 250 dBA lower than the turbulent flow. Studies on the tanks during fueling show that accumulated electric charge has its maximum at the central axis and the charge is increasing with the filling of the tank.
