Incompressibility
31Steam locomotive — A steam locomotive is a locomotive powered by steam. The term usually refers to its use on railways, but can also refer to a road locomotive such as a traction engine or steamroller.Steam locomotives dominated rail traction from the mid 19th… …
32Bathyscaphe — [ Bathyscaphe Trieste, before a dive into the Marianas Trench] A bathyscape, bathyscaphe, or bathyscaph is a free diving self propelled deep sea diving submersible, consisting of a crew cabin similar to a bathysphere suspended below a float… …

34Incompressible flow — In fluid mechanics or more generally continuum mechanics, an incompressible flow is solid or fluid flow in which the divergence of velocity is zero. This is more precisely termed isochoric flow. It is an idealization used to simplify analysis. In …
35D'Alembert's paradox — In fluid dynamics, d Alembert s paradox (or the hydrodynamic paradox) is a contradiction reached in 1752 by French mathematician Jean le Rond d Alembert.[1] D Alembert proved that – for incompressible and inviscid potential flow – the drag force… …
36Allen Hatcher — Allen Edward Hatcher is an American topologist and also a noted author. His book Algebraic Topology , which is the first in a series, is considered by many to be one of the best introductions to the subject.He received his Ph.D. under the… …
37P-wave — This article is on the type of seismic wave. For the term used in electrocardiography, see P wave (electrocardiography). P wave can also refer to a type of electronic wavefunction in atomic physics; see atomic orbital. Plane P wave …
38Boride — In chemistry a boride is a chemical compound between boron and a less electronegative element. This is a very large group of compounds that are generally high melting and are not ionic in nature. Some borides exhibit very useful physical… …
39Enstrophy — In fluid dynamics, the enstrophy mathcal{E} can be described as the integral of the square of the vorticity eta given a velocity field mathbf{u} as,: mathcal{E}(mathbf{u}) =frac{1}{2} int {S} eta^{2}dS. Here, since the curl gives a vector field… …
40Residence Time Distribution — The residence time distribution (RTD) of a chemical reactor is a probability distribution function that describes the amount of time a fluid elements could spend inside the reactor. Chemical engineers use the RTD to characterize the mixing and… …
