What should be measured to determine the effectiveness of the pump's performance?

To assess the effectiveness of a pump's performance, both flow rate and pressure must be measured. The flow rate indicates how much water is moving through the pump in a given time, reflecting the pump's ability to deliver water to the required locations. This is crucial for determining whether the pump can meet the demands of the firefighting operations.

Simultaneously, measuring pressure is essential because it reveals how much force the pump is generating to move the water through hoses and nozzles. Pressure affects the distance and reach of the water stream, which is critical during firefighting efforts.

By analyzing both flow rate and pressure together, operators can accurately evaluate the pump's performance. High flow with low pressure might indicate issues like clogged lines or open valves, while low flow and low pressure could suggest pump cavitation or mechanical failure. Therefore, a comprehensive assessment that includes both measurements provides a complete picture of pump performance, ensuring effective firefighting operations.
