Likewise, drag on an airfoil is defined as the force acting on an ... In fact, it is probably the most accurate method available for measuring flow velocity on a routine basis, and accuracies better ...

Whether the flow is viscous-drag dominated or pressure-drag dominated depends entirely ... For a given frontal area and velocity, a streamlined body will always have a lower resistance than a bluff ...

(a) The velocity of flow, q, changes only slightly for large ... In this case any flow method would be incapable of showing the 'viscous drag' of the liquid. With regard to the suggestion that ...
