Fluid Dynamics

coefficient of discharge depends on the state of the machine/system you are using.

if you are using very textured tubes then this number will be higher. if how ever you are using very flexable tubes and fluid at different pressures this can also effect your results as the inflow and outflow may be different, or the cross sectional area of the tubes again chganging the pressure/flow and thus you Cd value

Experimental fluid dynamics is a branch of fluid dynamics that involves conducting experiments in a controlled environment to study the behavior of fluids. Researchers use physical models, scaled-down prototypes, and advanced measurement techniques such as lasers and sensors to understand flow behaviors, turbulence, and other fluid phenomena. The data collected from these experiments help validate theoretical models and improve our understanding of how fluids interact with objects and surfaces.

Fluid friction occurs between layers within a fluidthat are moving relative to each other.

If straightened out, the top surface of the wing is longer than the bottom one. When air flows over the wing, it must travel faster over the top of the wing so there is less air pressure. higher air pressure on the bottom and lower air pressure on the top= LIFT. The higher the Airspeed the lower the air pressure is called Bernoulli's principle.

Hydrodynamics is the study of motion in liquids while aerodynamics is the study of motion in gases. But both of them are part of the study of fluid dynamics.

if the density of the fluid changes with respect to pressure is called compressible fluid

f the density of the fluid does not changes with respect to pressure is called

incompressible fluid

Mercury is better because 1) it doesn't evaporate 2) water has a density 13.6 times lower than mercury, so for some applications the size of the manometer would have to be very large.

the highest temperature at which a substance can exist as a liquid , is called its critical temperature .

e.g

critical temperature of carbon dioxide is 31.142 degree centigrade .

You can find pictures and explanations of 25 common laboratory apparatus on educational websites, scientific equipment suppliers' websites, or in laboratory equipment manuals. Additionally, you can check scientific textbooks or online databases such as ScienceDirect for detailed information on the functions of each apparatus.

Yes and no it madders if the shampoo has a strong enough sent like perfume and you inhale to much its like a drug acept a diffrent affect on your body and that affect is getting high.

Yes it is not possible. Because as soap is added then surface tension would get reduced and so possibility of float becomes less. When we carefully place the same needle on ordinary water floating is quite possible as water has more surface tension

If you slam on the brakes of your car, a helium-filled balloon will move towards the BACK of the car.

Since helium is lighter than air, a helium-filled balloon will float in air. This is an example of Archimedes Principle. This principle was first described by Archimedes, in the third century BC - the balloon experiences a buoyant force equal to the density of air times the volume of the balloon times the acceleration due to gravity, or

FB = p V g,

This buoyant force is directed OPPOSITE the direction of gravity (UP, whenever gravity is pointed DOWN).

Fast-forward 23 centuries, to 1907, when a young patent clerk named Albert Einstein first described something called the Equivalence Principle. This principle, the foundation of the Theory of General Relativity, states that it is impossible to distinguish between an accelerated reference frame and a gravitation-like force. In English, that means that a car decelerating (like when you slam on the breaks) feels and looks to everyone and everything inside the car as if there is a force of gravity towards the FRONT of the car. Heavy objects (like the driver, the passengers, and any loose objects sitting on the dashboard) act as if they are 'falling' forwards ('falling' in the direction of this 'gravity'). The helium-filled balloon will move towards the BACK of the car, because it will 'float' in the direction OPPOSITE this gravity.

That happens when - as is the case in a gas for example - the distribution of probabilities, when graphed, is not symmetric. The "most probable particle speed" probably refers to the maximum of the curve, and this is not necessarily equal to the average.

Because it's the ratio of two densities ... the density of the substance of interest

to the density of water.

In any ratio, the units of both quantities are the same, so the ratio winds up being

a dimensionless number.

Surface Tension

1/2 OD or ID as copper is measured by OD BUT in plumbing rather then saying 5/8 L tubing we say 1/2 BUT 1/2 in ACR work is actually plumbers 3/8

The flow rate is about 7.5 to 10gpm Plenty for up to 3 low flow shower heads.

Yes if the surface tension of the water is not broken. If you are careful you can place a needle on the surface of the water in a glass. Also if you reduce the surface tension with detergent (just a very little is enough) the needle will sink because it's density is greater than that of the water.

NO (if the surface tension of the water is broken, a needle cannot float on the surface of water. This is because the needle has higher density than water (density is mass divided by volume).

Applications of fluids could mean many different things. In medicine, this could refer to an intravenous infusion of saline. In the automotive world, this phrase could be used in reference to oil, gasoline, and other fluids used to maintain an engine.

Centrifugal and axial compressors will surge when forward flow through the compressor can no longer be maintained, due to an increase in pressure across the compressor, and a momentary flow reversal occurs. Once surge occurs, the reversal of flow reduces the discharge pressure or increases the suction pressure, thus allowing forward flow to resume again until the pressure rise again reaches the surge point. This surge cycle will continue until some change is made in the process or compressor conditions.

Critical velocity is that The Liquid Air flow in narrow pipe constatly.

Yes - a Newtonian fluid (or just a fluid) is one that continues to flow regardless or forces acting on it, and is only governed by temperature and pressure. Gas certainly 'flows' without the use of force: a gas will fill an unoccupied room without any external forces.
