### (a) Explanation of an Eductor and its Applications
An eductor, also known as a jet pump or ejector, is a simple, robust device designed to pump or transfer fluids using the kinetic energy of a motive fluid, without any moving parts. Its primary function is to create a low-pressure zone (vacuum) to entrain a second fluid (suction fluid) and then discharge the mixture against a higher pressure.
**Function:**
* **Fluid Transfer:** To pump liquids from a lower to a higher level or through a system, especially effective in scenarios where traditional mechanical pumps might struggle (e.g., high suction lift, presence of solids, corrosive fluids). They can handle large volumes of fluid due to their high capacity.
