Bernoulli's principle 3d animation
This is an important principle involving the movement of a fluid through a pressure difference. Suppose a fluid is moving in a horizontal direction and encounters a pressure difference. This pressure difference will result in a net force, which by Newton's 2nd law will cause an acceleration of the fluid. The fundamental relation,which is known as Bernoulli's principle. This is very similar to the statement we encountered before for a freely falling object, where the gravitational potential energy plus the kinetic energy was constant (i. e., was conserved).
Bernoulli's principle thus says that a rise (fall) in pressure in a flowing fluid must always be accompanied by a decrease (increase) in the speed, and conversely, if an increase (decrease) in , the speed of the fluid results in a decrease (increase) in the pressure. This is at the heart of a number of everyday phenomena. As a very trivial example, Bernouilli's principle is responsible for the fact that a shower curtain gets ``sucked inwards'' when the water is first turned on. What happens is that the increased water/air velocity inside the curtain (relative to the still air on the other side) causes a pressure drop. The pressure difference between the outside and inside causes a net force on the shower curtain which sucks it inward. A more useful example is provided by the functioning of a perfume bottle: squeezing the bulb over the fluid creates a low pressure area due to the higher speed of the air, which subsequently draws the fluid up. This is illustrated in the following figure.

The smaller pipe is lifted so at a certain height it will have the same flow rate as the large pipe. Conservation of energy.. turn your garden hose on, lift the nose 10 feet into the air and tell me you don't notice a velocity decrease. Smaller cross sectional area will increase the speed, greater height will decrease speed.

Never do all particles of a fluid travel along the same path as their preceding particle with the same velocity (0:03). That just doesn't happen. The particles move chaotically/in all directions, it's just that if the fluid is moving, there is a NET motion in the direction of movement, with most of the particles' motion still being chaotic (i.e. in all directions). 'Velocity' by itself is ambiguous, it could mean one of two things. It could be instantaneous velocity, or average velocity (displacement over some non-infinitesimal time period). It cannot be instantaneous velocity: The particles of static air at 300 K (~27 degrees Celsius) travel chaotically with an average speed of around 500 m/s (if you don't believe me, look it up!). Now, let's say that this static air is accelerated to this 'streamline flow' (0:03), where 'each particle has the same velocity', and let's say the new flow velocity is 5 m/s. If each particle has the same instantaneous velocity and the flow velocity is 5 m/s, then each particle must have an instantaneous velocity of 5 m/s. No other value would result in a flow velocity of 5 m/s. This means each particle must be going in the same direction (direction of flow) and have a speed of 5 m/s. This would equate to a drop in speed from 500 m/s (static air) to 5 m/s (flowing air), a factor of 100. Thus, the average kinetic energy would have decreased by a factor of 100 squared = 10,000. Since temperature (K) is proportional to average kinetic energy (as shown by the equation KE(avg) = 1.5 k T, where k is the Boltzmann constant), then this would result in the temperature's decreasing by a factor of 10,000. 300K / 10,000 = 0.03K, which is colder than the freezing point of all air's gaseous constituents at standard pressure (even of helium). No such acceleration of air achieves this temperature drop. So what about average velocity? I doubt that 'average velocity' is what was meant, because of the statement that the particles 'travel the same paths as their preceding particles' and the fact that the animation shows particles moving with the same instantaneous velocities as each other. However, even if 'average velocity' is what was meant, it is still not true: Since velocity is displacement over time, the particles can still be bouncing around mostly chaotically (as they do) and also have displacements over a non-infinitesimal time period: average velocities. However, for every single particle to have the same average velocity is a statistical impossibility. In reality, the particles will always have a range of different displacements after any given time, making up a distribution of different average velocities. Perhaps for some forms of fluid motion, most particles will have a similar average velocity over some values of time (IDK), but it will never be the same for all particles. Also, if 'average velocity' is what was meant, then the statement that all particles have the same velocity is meaningless, because the average velocity would vary depending on the time period over which it's calculated (this is due to the chaotic nature of the particle motion), and the time period is not given.

@Chris-rb8ox Жыл бұрын

@@arxalier2956 lol I admit I belabored the point there. That aside, to respond to your sassy rhetorical question, which you probably thought was clever at the time, yes I have heard of approximations and use them all the time, but as I showed very clearly before, the statement that all particles in a streamline move at the same velocity in streamline flow doesn't even come close to being approximately true. It's absolutely false. At best it's a lazy attempt at an abstraction that teachers use instead of explaining it properly, or because they don't understand it themselves, which I suspect is usually the case. To make it less incorrect you'd have to define 'particle' to mean 'small sample volume of fluid' or something, but that would be misleading because that's not what a particle is. A true statement/definition would be something like: 'the velocity of the fluid at every point along the streamline is approximately the same'. It might seem pedantic, but the statements are vastly different.

@Chris-rb8ox Жыл бұрын

@@sidharth5746 yup. Given the context, this rhetorical question seems to imply that laminar flow is by definition a flow in which all particles along a streamline have the same velocity and that therefore I'm incorrect in saying that this is not true. However, that's not what laminar flow is. Lamina flow is when the fluid is moving at the same velocity at all points along a streamline, not when all particles are moving at the same velocity along a streamline. I've showed that the latter is impossible with the relation of the kinetic energy of a fluid's particles to the fluid's temperature. In 5m/s flow, for example, if all particles were moving at that velocity or similar velocities, the 'fluid' would be at less than 1 Kelvin. That is obviously not what happens in 5m/s laminar flows IRL, and therefore the claim about equal particle speeds is false.
