Calculate the Froude number (froudeNum
) (dimensionless).

froudeNum
(vector of numericals, dimensionless)
The Froude number is a dimensionless coefficient that relates a vessel's speed
and length to a relative resistance. The equation for the Froude number is:
$$Fn=\frac{V}{\sqrt{g*Lwl}}$$
Where V is the ship's speed, g is the gravitational constant (9.81 m/s^2),
and lwl
is the waterline length (m) of the vessel.
