Question

If a fluid has a Reynolds number of 5000 in a pipe. The type of flow is

• A. Laminar flow
• B. Transitional flow
• C. Turbulent flow
• D. Irrotational flow

Hint:

Pipe Flow Regimes (Re).<2300 Laminar, 2300-4000 Transition,>4000 Turbulent.

Answer 1

The Correct Option is C

For fluid flow inside a circular pipe, the flow regime is typically characterized by the Reynolds number (Re): - Re<~2300: Laminar flow - ~2300<Re<~4000: Transitional flow - Re>~4000: Turbulent flow A Reynolds number of 5000 is greater than 4000, indicating that the flow is turbulent.
Irrotational flow describes the rotation of fluid elements and is not directly determined solely by the Reynolds number in this way.
