Because the inlet pressure is high, the flow rate is high.
Dear, please improve the title! so that more sea friends can participate
How do you post a two-word title? . . . . . . . . .
As the water level rises, the pressure at the pump inlet increases, the required head decreases, and thus the flow rate of the centrifugal pump increases
As the inlet pressure increases, with the pump’s work remaining unchanged, the required head decreases, resulting in an increase in flow rate
The inlet resistance has been reduced, resulting in an increase in flow rate
