The Richardson number is defined as Ri =L5g Δρ / ρV .2 Miguel is working on a problem that has a characteristic length scale L, a characteristic velocity V, a characteristic density difference Δ? , a characteristic (average) density ? , and of course the gravitational constant g, which is always available. He wants to define a Richardson number, but does not have a characteristic volume flow rate. Help Miguel define a characteristic volume flow rate based on the parameters available to him, and then define an appropriate Richardson number in terms of the given parameters.
