For a large orifice, the flow velocity profile is best described as
11. For a large orifice, the flow velocity profile is best described as:
- Uniform across the orifice
- Irregular and turbulent
- Parabolic across the orifice
- Inversely proportional to the orifice diameter
Answer: A) Uniform across the orifice
Explanation:
A large orifice has a flow velocity profile almost uniform throughout the orifice. This occurs as a result of the orifice geometry having less of an impact on the flow than smaller orifices.
