However a more simple equation relating only the different energies in the fluid, known as Bernoulli's equation can be used.

The simple form of Bernoulli's principle is valid for incompressible flows ( e. g. most liquid flows ) and also for compressible flows ( e. g. gases ) moving at low Mach numbers.

The simple treaty principle that Gabriel was asking him to ratify, in short, was nothing less than total trust.

simple: Anthropic principle

Although computing a power spectrum from a map is in principle a simple Fourier transform, decomposing the map of the sky into spherical harmonics, in practice it is hard to take the effects of noise and foreground sources into account.

In principle, the constitutionality of laws in Finland is verified by a simple vote in the parliament ( see Parliamentary sovereignty ).

While the description of strong and weak interactions within the Standard Model is based on gauge symmetries governed by the simple symmetry groups SU ( 3 ) and SU ( 2 ) which allow only discrete charges, the remaining component, the weak hypercharge interaction is described by an abelian symmetry U ( 1 ) which in principle allows for arbitrary charge assignments.

The narrative structure allows for this diversity through simple stylistic devices such as the principle of ring composition, familiar since the time of Homer, in which the introduction and conclusion of a story or sub-plot is signalled by the repetition of some formulaic statement, facilitating the reader's comprehension of stories within stories in a kind of ' Chinese-box technique '— a structure that has no resemblance to the nine books artificially created by Alexandrian scholars.

A simple example of the operation of the principle can be seen when two rooms are connected by an open doorway and a sound is produced in a remote corner of one of them.

KISS is an acronym for the design principle articulated by Kelly Johnson, Keep it simple stupid !.

" The KISS principle states that most systems work best if they are kept simple rather than made complex, therefore simplicity should be a key goal in design and unnecessary complexity should be avoided.

simple: KISS ( principle )

Instead of didactic teaching, they stress a simple Neopagan principle: " Find the Divine within your own experience.

In the absence of nonlinear effects, the superposition principle can be used to predict the shape of interacting waveforms through the simple addition of the disturbances.

The claimed principle was simple: export of munitions — guns, bombs, planes, and software — was ( and remains ) restricted ; but the export of books is protected by the First Amendment.

Thus followed the line of Lomonosov and the contributions of the Russian school became more frequent through his disciples, and in the nineteenth century we have great geographers as Vasily Dokuchaev who performed works of great importance as a " principle of comprehensive analysis of the territory " and " Russian Chernozem " latter being the most important where introduces the geographical concept of soil, as distinct from a simple geological strata, and thus founding a new geographic area of study: the Pedology.

simple: Pauli exclusion principle

Security through obscurity has never achieved engineering acceptance as an approach to securing a system, as it contradicts the principle of " keeping it simple ".

Hence, Aquinas acknowledges the principle which today is known as Occam's Razor, but prefers causal explanations to other simple explanations ( cf.

This property, called the principle of superposition, is very useful, e. g., solutions to complex problems can be constructed by summing simple solutions.

For example, Sir Arthur Stanley Eddington claimed that the cosmological constant version of the vacuum field equation expressed the " epistemological " property that the universe is " self-gauging ", and Erwin Schrödinger's pure-affine theory using a simple variational principle produced the field equation with a cosmological term.

The core principle of spread spectrum is the use of noise-like carrier waves, and, as the name implies, bandwidths much wider than that required for simple point-to-point communication at the same data rate.

In The Elements of Style ( 1918 ), William Strunk concentrated on specific questions of usage — and the cultivation of good writing — with the recommendation " Make every word tell "; hence, the 17th principle of composition is the simple instruction: " Omit needless words.

In file systems lacking such naming mechanisms, drive letter assignment proved a useful, simple organizing principle.

The principle behind the nuclear ramjet was relatively simple: motion of the vehicle pushed air in through the front of the vehicle ( ram effect ), a nuclear reactor heated the air, and then the hot air expanded at high speed out through a nozzle at the back, providing thrust.

In 1738 The Dutch-Swiss mathematician Daniel Bernoulli published Hydrodynamica, in which he described the fundamental relationship among pressure, density, and velocity ; in particular Bernoulli's principle, which is one method to calculate aerodynamic lift.

At the speed of sound the way that lift is generated changes dramatically, from being dominated by Bernoulli's principle to forces generated by shock waves.

This pressure difference is accompanied by a velocity difference, via Bernoulli's principle, so the resulting flowfield about the foil has a higher average velocity on one side than the other.

Bernoulli's principle states that within an airflow of constant energy, when the air flows through a region of lower pressure it speeds up and vice versa.

Bernoulli's principle states that this pressure difference must be accompanied by a speed difference.

Bernoulli's principle does not explain why the air flows faster over the top of the wing ; to explain that requires some other physical reasoning.

If one takes the experimentally observed flow around an airfoil as a starting point, then lift can be explained in terms of pressures using Bernoulli's principle and conservation of mass.

From Bernoulli's principle, the pressure on the upper surface where the flow is moving faster is lower than the pressure on the lower surface where it is moving slower.

* In deriving Bernoulli's principle, assumptions may be made ( such as constant energy or incompressible flow ) that are not applicable to real-world airfoils.

* A common explanation using Bernoulli's principle asserts that the air must traverse both the top and bottom in the same amount of time and that this explains the increased speed on the ( longer ) top side of the wing.

By Bernoulli's principle, this implies a pressure difference and therefore lift.

Since the flow speed is zero at these points, by Bernoulli's principle the static pressure at these points is at a maximum.

While this theory depends on Bernoulli's principle, the fact that this theory has been discredited does not imply that Bernoulli's principle is incorrect.

The force on the wing can be examined in terms of the pressure differences above and below the wing, which can be related to velocity changes by Bernoulli's principle.

One method for calculating the pressure is Bernoulli's equation, which is the mathematical expression of Bernoulli's principle.

Bernoulli's principle provides an explanation of pressure difference in the absence of air density and temperature variation ( a common approximation for low-speed aircraft ).

Bernoulli's principle, by including air velocity, explains this pressure difference.

* Bernoulli's principle

This conversion of kinetic energy to pressure can be explained by the First law of thermodynamics or more specifically by Bernoulli's principle.

Propeller dynamics can be modelled by both Bernoulli's principle and Newton's third law.

A tornado is not necessarily visible ; however, the intense low pressure caused by the high wind speeds ( as described by Bernoulli's principle ) and rapid rotation ( due to cyclostrophic balance ) usually causes water vapor in the air to condense into cloud droplets due to adiabatic cooling.
