Reference Answer
The operational characteristics of a centrifugal pump are critically defined by its discharge curves, which illustrate the relationship between the pump's capacity (flow rate) and the head developed, power consumed, and efficiency. Understanding these characteristics is fundamental for proper selection, operation, and troubleshooting of centrifugal pumping systems.
### I. Discharge Characteristics of a Centrifugal Pump
Centrifugal pump discharge characteristics are typically represented by a set of curves plotted against the pump's capacity (flow rate). These curves describe:
* **Head-Capacity (H-Q) Curve:** Represents the total dynamic head the pump can generate at various flow rates.
