Inviscid flow Inviscid flow Inviscid flow is the flow of an inviscid fluid, in which the viscosity of the fluid is equal to zero. Though there are limited examples of inviscid fluids, known as superfluids, inviscid flow has many applications in fluid dynamics. The Reynolds number of inviscid flow approaches infinity as the viscosity approaches zero. When viscous forces are neglected, such as the case of inviscid flow, the Navier-Stokes equation can be simplified to a form known as the Euler equation. This simplified equation is applicable to inviscid flow as well as flow with low viscosity and a Reynolds number much
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.
