THE CONCEPT OF VISCOSITY - Columbia University

negative value of the velocity gradient between the two layers. An alternative interpretation can be given to (3.1.3) by noting, from elementary physics, that Force = mass × acceleration = mass × velocity/time = = momentum/time Therefore, (3.1.3) also states that the rate of momentum transfer per unit

angular velocityangular velocity Ωaboutthezaxisabout the z axis. • In this case, U R, where R is the distance from the axis of rotation to the ring of fluid. Thus the circulation about the ring is given by: • In this case the circulation is just 2 π times the angular momentum of the fluid ring about the axis of rotati on. Alternatively ...
