Exam Question

A centrifugal pump operates on the principle of converting rotational kinetic energy from an impeller into hydrodynamic energy of the fluid. This energy conversion results in increased fluid velocity and pressure, propelling the fluid through the discharge.
### Discharge Characteristics of a Centrifugal Pump
The performance characteristics of a centrifugal pump are typically represented by a series of curves plotted against capacity (flow rate, Q) on the x-axis. These curves illustrate how the pump's performance parameters change with varying flow rates and are crucial for pump selection and system design. A "suitable graph" would typically include the following curves:
