Question

Match List-1 with List-2 and select the correct answer using the codes given below the lists:
List-1
A. Froude number
B. Euler number
C. Reynolds number
D. Mach number

List-2
1. Related to inertia force and elastic force
2. Related to inertia force and viscous force
3. Related to inertia force and pressure force
4. Related to inertia force and gravity force

• A. A-4, B-1, C-3, D-2
• B. A-2, B-3, C-4, D-1
• C. A-4, B-3, C-2, D-1
• D. A-2, B-1, C-4, D-3

Answer 1

The correct option is C A-4, B-3, C-2, D-1

The Froude number is a ratio of inertial and gravitational forces. The Euler Number can be interpreted as measure of the ratio of the pressure forces to the inertial forces. Reynolds is the ratio of inertia force to viscous force. Mach number is ratio of inertia force to elastic force.
