Question

The speed (v) of ripples depends upon their wavelength (λ), density (ρ) and coefficient of viscosity (η) of water. Then speed depends upon what power of coefficient of viscosity (η)?​

Answer 1

Answer:

Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion. For instance, when a fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. In such a case, experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow through the tube. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion: the strength of this force is proportional to the viscosity.
