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? (novel) What Is to Be Done? (novel) What Is To Be Done? (; also translated as What Shall We Do? and literally translated as "What To Do?") is an 1863 novel written by the Russian philosopher, journalist and literary critic Nikolai Chernyshevsky. It was written in response to "Fathers and Sons" (1862) by Ivan Turgenev. The chief character is a woman, Vera Pavlovna, who escapes the control of her family and an arranged marriage to seek economic independence. The novel advocates the creation of small socialist cooperatives based on the Russian peasant commune, but oriented toward industrial production. The author promoted
