An important parameter in certain types of fluid flow problems when a free surface is present is the Froude number (Fr), which can be expressed in equation form as (Fr) = [pv^2/Lw]^1/2 where p is the density of the fluid, v is a velocity, L is a length, and w is the specific weight of the fluid. Show that the Froude number is dimensionless
