Tau tensor
Wall shear stress expresses the retarding force (per unit area) from a wall in the layers of a fluid flowing next to the wall. It is defined as: Where is the dynamic viscosity, the flow velocity and the distance from the wall. It is used, for example, in the description of arterial blood flow in which case which there is evidence that it affects the atherogenic process. WebJun 11, 2013 · 1 Answer. After a "long time" the capacitor will charge to a voltage that is slightly less than 12V. This voltage is approximately 10.909V and this value is determined …
