In a centrifugal pump, increasing the head will generally cause the discharge to ___.

Explanation:
In centrifugal pumps, the operating point is found where the pump’s head curve intersects the system’s head curve. The pump head produced at a given speed typically decreases as flow increases, while the system head (resistance) tends to rise with more flow. So, when the system requires more head, the intersection moves toward a lower flow, meaning the discharge drops. In short, increasing the head the system must overcome pushes the operating point to a smaller flow, reducing discharge.
