In a relay pump operation, it is desirable to maintain the minimum __________ pressure at the next pumper in line.

In a relay pump operation, maintaining the minimum intake pressure at the next pumper in line is crucial for ensuring that each pumper operates efficiently and effectively. The intake pressure is the pressure within the suction side of the pump and is necessary for the pump to draw water correctly. If the intake pressure is too low, it could lead to cavitation, which can damage the pump and impair its ability to maintain water flow.

This operation typically involves multiple pumpers working together to cover long distances or to boost pressure, and each unit relies on a favorable intake pressure to perform optimally. The goal is to keep the water flowing smoothly from one pump to the next without dropping pressure significantly, as this would impact the entire operation. Therefore, focusing on maintaining adequate intake pressure helps ensure the overall effectiveness of the relay pumping operation.
