The Commercial airplane has two tanks which are placed in its wing, and one fuel tank for each wing. The engines of the plane draw the fuel from each wing. To keep the plane equilibrated the draw of the fuel must be at the same rate; i. e the fuel mass on both wings must be the same. Sometimes, when one fuel tank gets a hole for some reason. This leads to a leak in the fuel from that tank. The system must draw as much as it can fuel from that tank and pump it to the other tank to give the airplane as much time as it can to provide the plane with as much as it can from the fuel to reach the most possible emergency airport. Draw an activity diagram.
