Reference Answer
### (a) Description of Pump Terminology
#### (i) Flow Rate (Capacity)
* **Definition**: Flow rate, often referred to as capacity, is the volume of liquid that the pump moves through a system per unit of time. It quantifies the pump's output volume.
* **Factors**: The actual flow rate is determined by the pump's design (impeller diameter, speed) and the characteristics of the system it is operating in, specifically the total system head (resistance).
