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
What Is to Be Done? what Lenin’s real views were". Therefore, Lih argues, the word спонтанность, when translated as "spontaneity", distorts his views and has different contextual connotations; how конспирация does not mean "conspiracy", but "the rules and procedures needed for an underground organisation to survive"; тред-юнионизм does not mean "trade unionism", but non-revolutionary "only trade unionism"; and революционер по профессии should not be translated as "professional revolutionary". What Is to Be Done? What Is To Be Done? Burning Questions of Our Movement () is a political pamphlet written by the Russian revolutionary Vladimir Lenin (credited as N. Lenin) in 1901 and published in 1902.
