Question:
For which of the following Reynold's number, a flow is streamlined?
For which of the following Reynold's number, a flow is streamlined?
Show Hint
To avoid confusion across different textbooks, always pick the most extreme appropriate value. A Reynolds number below \(1000\) is universally accepted as completely laminar flow under almost all standard fluid dynamics conventions.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
The question asks us to identify the Reynolds number value associated with streamlined (laminar) flow.
Step 2: Detailed Explanation:
The flow of fluid in a pipe depends fundamentally on its Reynolds number (\(Re\)). The broadly accepted empirical regimes are:
Step 3: Final Answer:
The flow is streamlined at a Reynolds number of \(900\).
The question asks us to identify the Reynolds number value associated with streamlined (laminar) flow.
Step 2: Detailed Explanation:
The flow of fluid in a pipe depends fundamentally on its Reynolds number (\(Re\)). The broadly accepted empirical regimes are:
- \(Re<2000\): Flow is steady, orderly, and streamlined (laminar).
- \(2000 \le Re \le 3000\): Flow is unstable and in the transitional regime.
- \(Re>3000\): Flow becomes highly disorganized and turbulent.
Step 3: Final Answer:
The flow is streamlined at a Reynolds number of \(900\).
