1972). The measurements will address several fundamental questions in the field of fluid mechanics, including the friction factor and the von Karman's constant dependence on Reynolds number, the inner ...

This friction is associated with the development of boundary layers, and it scales with Reynolds number as we have seen above. Pressure drag comes from the eddying motions that are set up in the fluid ...

The correct answer is A, "viscosity." The Reynolds Number for a flowing fluid can be generalized as the ratio of kinetic (or inertial) forces divided by viscous forces. Although friction factor and ...
