If you are bunkering and you close off one tank in the line of tanks being filled, the rate of flow to other open tanks on the same line will?

When bunkering operations involve filling multiple tanks from a common line, the flow dynamics can be influenced by the status of each tank in that line. When one tank is closed off, it effectively reduces the overall volume of space requiring filling, which can lead to an increase in the flow rate to the remaining open tanks.

This occurs because the pump is still generating the same pressure and flow rate; however, with one tank closed, the other tanks are now receiving a larger portion of the available flow. The restriction has created a situation where the fluid dynamics allow for more efficient flow into the open tanks, which can result in an increased flow rate to those tanks.

This understanding is crucial for safety and operational efficiency during bunkering. It's important to monitor the flow rates carefully to ensure that the tanks being filled do not overflow or experience pressure-related issues, as the dynamics of fluid movement can change significantly with the configuration of open and closed tanks.
