Topic: Fluid Mechanics
Match List I with List II and select the correct answer
List I (Forces)
1. Reynolds number
2. Froude number
3. Weber number
4. Mach number
List II (Dimensionless groups)
A. Viscous Force
B. Elastic force
C. Surface tension
D. Gravity
- A. 1-A, 2-B, 3-C, 4-D
- B. 1-A, 2-D, 3-C, 4-B
- C. 1-A, 4-B, 3-C, 2-D (Matches formatted as C in text)
- D. 2-A, 1-B, 3-C, 4-D
Explanation: The correct matches are: Reynolds number is ratio of inertia to Viscous Force (1-A). Mach number relates to Elastic force (4-B). Weber number relates to Surface tension (3-C). Froude number relates to Gravity (2-D).
