Can you give an example of both Reynolds and Froude numbers?

The correct answer to this question is the Motion of ships in rough seas. Made popular by Osborne Reynolds, Reynolds numbers are calculated by using the formula Re= pvl over u = vl over v. In this formula, V represents the velocity of the fluid, l is the characteristic length, p is the density of the fluid, u is the dynamic viscosity of the fluid, and v is the kinematic viscosity of the fluid. Named after engineer William Froude, a Froude number is defined as Fr = v/(gd)1/2. G0 is the external field, u) is the flow velocity, and l0 is the characteristic length.
