Question

Group-I Contains dimensionless parameter and
Group-II contains ratio

Group-I
P. Mach number
Q. Reynold number
R. Weber number
S. Froude number
Group-II
1. Ratio of inertial force and gravity force.
2. Ratio of fluid velocity and velocity of sound.
3. Ratio of inertial force and viscous force.
4. Ratio of inertial force and surface tension force.
