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.
