An important dimensionless parameter in certain types of fluid flow problems is the Froude number defined as $\frac{V}{\sqrt[\phantom{2}]{gl}},$ where $V$ is a velocity, $g$ the acceleration of gravity, and $l$ a length. Determine the value of the Froude number for $V=12f\frac{t}{s},g=32\mathrm{.}2f\frac{t}{s^2},$ and $l=3ft.$ Recalculate the Froude number using $SI$ units for $V,g,$ and $l.$ Explain the significance of the results of these calculations.

In BG units: $\frac{V}{\sqrt[\phantom{2}]{gl}}=$
