2. Which orifice is used to monitor the flow of liquid from one reservoir to another under the influence of gravity?
- Submerged Orifice
- Internal Orifice
- External Orifice
- Eccentric Orifice
Answer: A) Submerged Orifice

A submerged orifice is placed below the surface of a liquid reservoir, and flow occurs due to the difference in liquid levels between the upstream and downstream sides. This kind of orifice is widely used for determining flow under gravity.
