coefficient of drag (CD)

A coefficient dependent upon the angle of attack, shape of the airfoil, Reynolds number, and Mach number. Drag coefficient (C_D) = Drag (D)/Dynamic Pressure (q) or {¼(Density (ρ) × Air Speed² (V²)} x Wing Area (S). C_D = D/qS, or 2D/ρV²S.

Here [rho] is the density of seawater (nominally 1025 kg [m.sup.-3]), U is water velocity (m [s.sup.-1]), S is maximal planform area ([m.sup.2], essentially half the wetted surface area of the frond), and [C.sub.d] is the dimensionless coefficient of drag. In a comparison of groups of algae taken from "exposed" and "protected" sites, Carrington (1990) found no significant difference in stipe strength (breaking force divided by cross-sectional area at the breaking point) for M.

To calculate the coefficient of drag, the Wrights created a "drift balance" to measure an angle they called the tangential, which "gives the inclination of the chord [of the wing] above or below the horizon."
