For slender columns, the influence of the drag force on the platform can be calculated by the Morison equation, and the drag force per unit length of column is (A-26)fD=12ρCDD(wx−x˙)|(wx−x˙)| where: D is the diameter of column; CD is the coefficient of drag force; wx ...
and other factors like the shape of the airfoil. Total drag is the sum total ofinduced dragand parasite drag. Drag (D) = Coefficient of drag (CD) x ¼ density (ρ) x square of relative speed (V2) x surface area (S); orD=CDqS, whereDis the drag,qthe dynamic pressure (¼ρV2...
Measurements of the drag coefficients are reported in this paper for six different geometrical shapes, including isometric, axisymmetric, orthotropic, plane and elongated conglomerates of spheres. From these measurements, a new and accurate empirical correlation for the drag coefficient, C D, of ...
The value of the drag coefficient, C , is determined empirically, usually with the use of a wind tunnel. (See Figure 2). Figure 2. NASA researchers test a model plane in a wind tunnel. (credit: NASA/Ames) The drag coefficient can depend upon velocity, but we will assume that it is...

The accurate assessment of drag results in economic design of automobiles, chimneys, towers, buildings, hydraulic structures etc. The present work is the result of extensive experimentation on cylindrical bodies with varying cylinder diameters and air velocity. The drag coefficient of a cylinder was ...

The polar of lift-to-drag ratio vs. lift coefficient is given in Fig. 14, showing that the enhanced lift by the GF is accompanied by a reduction in lift-to-drag ratio at low-to-moderate lift coefficient (Cl<1.2). The 90° flap had the lowest lift-to-drag ratio, while the 45° ...
of some other marker in the sample. If the stage is moved to generate the fluid flow, the velocity of the fluid surrounding the trapped object can be estimated from the motion of the stage. In either case, thedrag coefficient, from eqn[2]may need to be corrected if the trapped object ...
