# Hydrodynamics Sentence Examples

His researches in

**hydrodynamics**were highly useful for marine engineering, while the reflecting and repeating circles, as improved by him, were of great service in nautical astronomy.At a later period he was one of the leading contributors to the Encyclopaedia Britannica (seventh and eighth editions), the articles on Electricity,

**Hydrodynamics**, Magnetism, Microscope, Optics, Stereoscope, Voltaic Electricity, &c., being from his pen.Thus rational mechanics, based on the Newtonian Laws, viewed as mathematics is independent of its supposed application, and

**hydrodynamics**remains a coherent and respected science though it is extremely improbable that any perfect fluid exists in the physical world.One of the most successful labourers in the science of

**hydrodynamics**at this period was Pierre Louis Georges Dubuat (1734-1809).Two methods are employed in

**hydrodynamics**, called the Eulerian and Lagrangian, although both are due originally to Leonhard Euler.Now the kinetics of a medium in which the parts can have finite relative motions will lead to equations which are not linear - as, for example, those of

**hydrodynamics**- and the phenomena will be far more complexly involved.It is true that the theory of vortex rings in

**hydrodynamics**is of a simpler type; but electric currents cannot be likened to permanent vortex rings, because their circuits can be broken and the element of cyclic steadiness on which the simplicity depends is thereby destroyed.Given that such observations at the surface of the sea, at intermediate levels and at the bottom are sufficiently numerous and are of a high degree of precision, general conclusions as to the movements of the ocean may be deduced from established theorems in

**hydrodynamics**.Benedetto Castelli (1577-1644), and Evangelista Torricelli (1608-1647), two of the disciples of Galileo, applied the discoveries of their master to the science of

**hydrodynamics**.In particular, for a jet issuing into the atmosphere, where p=P, q 2 /2g = h - z, (9) or the velocity of the jet is due to the head k-z of the still free surface above the orifice; this is Torricelli's theorem (1643), the foundation of the science of

**hydrodynamics**.AdvertisementMoving Axes in

**Hydrodynamics**.His experiments and his treatise (written before 1651, published 1663) on the equilibrium of fluids entitle him to rank with Galileo and Stevinus as one of the founders of the science of

**hydrodynamics**.There are a number of studies that have developed mathematical models to predict the

**hydrodynamics**around culture operations to optimize selection 18.She is an expert in modeling biogeochemical process and coastal aquifer

**hydrodynamics**.Thus new material models and innovative methods such as smooth particle

**hydrodynamics**are utilized.AdvertisementThe experiment allows researchers to test models of the complex

**hydrodynamics**as these jets interact with the surrounding media.The theorems of hydrostatics are thus true for all stationary fluids, however, viscous they may be; it is only when we come to

**hydrodynamics**, the science of the motion of a fluid, that viscosity will make itself felt and modify the theory; unless we begin by postulating the perfect fluid, devoid of viscosity, so that the principle of the normality of fluid pressure is taken to hold when the fluid is in movement.By his mode of regarding a liquid as a material system characterized by the unshackled mobility of its minutest parts, the separation between the mechanics of matter in different forms of aggregation finally disappeared, and the fundamental equation of forces was for the first time extended to hydrostatics and

**hydrodynamics**.'The branch of

**hydrodynamics**which discusses wave motion in a liquid or gas is given now in the articles Sound and Wave; while the influence of viscosity is considered under Hydraulics.Now it is shown in

**hydrodynamics**that she velocity of propagation of waves in deep water is that acquired by a heavy body falling through half the radius of the circle whose circumference is the wave-length, or _ f_X _ ga 27rT 'I ' v2- 2r 2r pn This velocity is a minimum when X=2.7r gp' and the minimum value is v= 4 - p g For waves whose length from crest to crest is greater than X, the principal force concerned in the motion is that of gravitation.Advertisement
