... Drag= Cd x q x A There is a similarity between lift coefficient and drag coefficient in that the lift coefficient, CL , is a measure of how much of the dynamic pressure gets converted into lift, and the drag coefficient is a measure of how well a wing (or other body) converts dynamic pressure force ...

... few simple cases, the value of α can be computed analytically. For example, in the case of a sphere of radius r moving slowly through a fluid, it can be shown that fdiss = 6πrηv . Usually, however, no simple formula exists, and α must be determined experimentally. The second term is more appropriate ...

... The lift force is thus forced to be proportional to V and not to V2 as assumed by R&R. This proportionality can also be derived using Bernoulli`s equation for a flow like that pictured in figure 1 in the paper by R&R. The flow in a not rotating frame of reference following the sphere is assumed to b ...
