Shear flow themselves. In a shearing flow, adjacent layers of fluid move parallel to each other with different speeds. Viscous fluids resist this shearing motion. For a Newtonian fluid, the stress exerted by the fluid in resistance to the shear is proportional to the strain rate or shear rate. A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other. Here, the strain rate is simply the relative velocity divided by the distance between the plates. Shear flows in fluids
Ability to benefit Ability to benefit Ability to benefit (ATB) is a term used in the context of post-secondary education in the United States to refer to students who have sufficient competency to benefit from post-secondary education but do not have a high school diploma or the Certificate of High School Equivalency. ATB, as assessed by government-approved tests, is required for receiving financial aid by most US public colleges that admit students without a high school diploma or the certificate of equivalency. Until July 2012, such students could also receive student loans and grants from the US government if they had passed an
