A single centrifugal pump will operate by itself (no parallel pump) to lift wastewater from a wet well to the plant headworks. The pump is running at constant speed. For this station, the pump curve and the system curve (static + friction) are provided in the tables. The plant influent today is about 1.3 MGD (extra information). Using linear interpolation between the closest table points, what is the expected operating point (flow and total dynamic head) where the pump curve intersects the system curve?
