Pump curves indicate which metrics?

Explanation:
Pump curves show how a pump performs across different flow rates. The key quantities are head (the pressure the pump can generate), the flow rate (gallons per minute, or gpm), and efficiency (how effectively the pump converts input power into hydraulic output at each point on the curve). These curves let you pick a pump that provides the required flow at the needed head while keeping energy use reasonable. Temperature, pH, and turbidity are water quality properties, not hydraulic performance data. Electrical values like voltage, current, and resistance describe the electrical side, not the pump’s hydraulic behavior. Maintenance interval is a service detail, not shown on a pump performance curve. So the metrics indicated by pump curves are head, efficiency, and gpm.
