If you are relating the levels of organization of the human body to the levels of organization of a city, what would you relate cells to? What would you relate the other levels to?

Closed-circuit wind tunnels can produce higher speeds than open-circuit tunnels with the same power input because energy is recovered in the diffuser downstream from the test section. The kinetic energy ratio is a figure of merit defined as the ratio of the kinetic energy flux in the test section to the drive power. Estimate the kinetic energy ratio for the 40 ft $\times$ 80 ft wind tunnel at NASA-Ames.
