Where is the inlet side of a mechanical vent connection located?

In a mechanical vent connection, the inlet side is defined as the area where the incoming air or gas enters the system. This is typically referred to as the inlet side to distinguish it from the outlet or exhaust side. Selecting the choice that indicates "the inlet side" correctly identifies the location of the vent connection where the air or gas enters before it is moved through the system.

Options that reference specific physical locations, such as "at the top" or "at the bottom," do not accurately represent the concept of the inlet side. Such locations could vary based on the design of the equipment or system being described. Instead, the term "inlet side" clearly conveys the functional aspect of the connection and is universally applicable across different configurations. Similarly, "at the junction points" could pertain to various connection locations within a system, but it does not specifically address the inlet side, which is the focus of the question. Therefore, emphasizing the term "inlet side" ensures clarity regarding the connection's purpose and position.
