Dimensionless Numbers

a) Reynold's number: It is the ratio of the inertia force to the viscous force.

b) Froude's number: It is the ratio of the inertia force to the gravity force.

c) Weber's number: It is the ratio of the inertia force to the surface tension force.

d) Euler's number: It is the ratio of the inertia force to the pressure force.

e) Mach's number or Cauchy's number: It is the ratio of the inertia force to the elastic force.
