Which term refers to the power and efficiency characteristics displayed on a pump curve?

• A. Head power
• B. Capacity
• C. Flow rate
• D. Lift

Answer: (B)

The term that refers to the power and efficiency characteristics displayed on a pump curve is capacity. In the context of a pump curve, capacity represents the volume of fluid that a pump can move over a specified period, typically measured in gallons per minute (GPM) or liters per second (L/s). The pump curve visually illustrates how the capacity changes with varying head (the height the fluid is lifted) and other factors like efficiency and power consumption. Understanding capacity is crucial for operators because it allows them to determine whether a pump can meet the demands of a specific application. This assessment ensures that the system operates effectively, minimizing energy waste and optimizing performance. The other terms mentioned, while related to pumps, do not specifically encompass the overall power and efficiency characteristics as capacity does.
