For instance, the flow around a circular cylinder generates a Kármán vortex street: vortices being shed in an alternating fashion from each side of the cylinder.

For a vortex line of infinite length, the induced velocity at a point is given by

For example, atmospheric cyclones are rotational but their substantially two-dimensional shapes do not allow vortex generation and so are not turbulent.

For example, the entire process of blowing out a candle by a puff of air is readily explained by vortex dynamics but is much more complicated to explain using the usual primitive variables of fluid flow theory such as pressure and velocity.

For instance, the lift distribution over a finite wing may be approximated by assuming that each segment of the wing has a semi-infinite trailing vortex behind it.

For example, a particle emitter used in conjunction with a star shape and the ' vortex ' behaviour would animate a circle of swirling stars.

For example, the geometry of the separator is not considered, the particles are assumed to achieve a steady state and the effect of the vortex inversion at the base of the cyclone is also ignored, all behaviours which are unlikely to be achieved in a cyclone at real operating conditions.

For many purposes a ring vortex may be approximated as having a vortex-core of small cross-section.

For example, Shafranov used a magnetohydrodynamic ( MHD ) analogy to Hill's stationary fluid mechanical vortex to consider the equilibrium conditions of axially symmetric MHD configurations, reducing the problem to the theory of stationary flow of an incompressible fluid.

For example, a research plasma torch at the Institute of Plasma Physics ( IPP ) in Prague, Czech Republic, functions with an H2O vortex ( as well as a small addition of argon to ignite the arc ), and produces a high temperature / velocity plasma flame.

For the next century or so vortex dynamics matured as a subfield of fluid mechanics, always commanding at least a major chapter in treatises on the subject.

For innocence, of all the graces of the spirit, is I believe the one most to be prayed for.

William Wimsatt and Cleanth Brooks, it seems to me, have a penetrating insight into the way in which this control is effected: `` For if we say poetry is to talk of beauty and love ( and yet not aim at exciting erotic emotion or even an emotion of Platonic esteem ) and if it is to talk of anger and murder ( and yet not aim at arousing anger and indignation ) -- then it may be that the poetic way of dealing with these emotions will not be any kind of intensification, compounding, or magnification, or any direct assault upon the affections at all.

For his part, Thompson had explained in a previous letter that there would be nothing but an honorable friendship between Katie and himself.

For them a box will be lodgment enough.

For them only a little more needed to be learned, and then all physical knowledge could be neatly sorted, packaged and put in the inventory to be drawn on for the solution of any human problem.

For this reason, then, poetry tends to weaken the power of control, the reason, because it tempts one to indulge his passions, and even the best of men, he maintains, may be corrupted by this subtle influence.

For him to divorce God and wife simultaneously would be bad publicity.

For a time it appeared that a common European army might be created, but the project for a European Defense Community was rejected by the French National Assembly in 1954.

For the most part, however, the new version is contemporary and, as such, should be the means for many to attain a clearer comprehension of the meaning of those words recorded so many hundreds of years ago by the first followers of Christ.

For those who `` like poetry but never get around to reading it '', the Library of Congress makes it possible for poets to be heard reading their own work.

For it is such a distinguished place, with such fine works of art and such a big library, that there can be little doubt but that the owner has become depraved by all this culture.

For the first time, he be sad about the move.

For petrographical purposes, tuff is generally classified according to the nature of the volcanic rock of which it consists ; this may be the same as the accompanying lavas if any were emitted during an eruption, and if there is a change in the kind of lava which is poured out, the tuffs also indicate this equally clearly.
