When a bottle is tilted to pour it's content, can it be called " A STREAM-LINE FLOW?"?

In general, if it's viscous enough that turbulence isn't a factor, yes.  I'd guess that the water stream would be turbulent near the mouth of the bottle while honey would not.

The answer is glass... glass is an amorphus solid, meaning that it has solid characteristics, but is technically "flowing"

The clast is rotating as it's being carried along in the water, and if it hits the substrate with its edge pointing down in the downstream direction, the clast will embed.  So when you're looking at a rock with embedded clasts in it, you can determine the direction of current by measuring the maximum down dip direction on the clasts.  In other words, if the clasts are all dipping down in a certain direction, that's the direction of streamflow when the rock was deposited.

You need to be a bit more specific about which quantities you are trying to determine.  "Flow" is not a quantity to be calculated.

when you have liquid in a container, particularly water, will curl up on the sides as it tries to expand it's surface area. in a volumetric flask or a graduated cylinder the meniscus will look like a little contact lens or a curve dipping down and when you are measuring things, the very bottom of the meniscus should be located at where you want the amount, (ie: 3 mLs.)

it's not that easy to define a "liquid" in a conventional way: take for example the glass for windows, it has its own volume and shape so we would define it a solid, but its microscopic disordered structure would make us call it a liquid! If we could wait ages we would see it flowing (as they say it happens for the windows in Chartres Cathedral.\nSo in material science liquid is a system that on ordinary observation time scale (years) shows a viscosity (the property of flowing  eg water is less viscous than honey) below 10^12 Pa*s

"Viscosity" is the degree to which a substance is fluid.\nIf a substance undergoes a decrease in viscosity when agitated, it is said to be "thixotropic."  The character of being thixotropic is called "thixotropy."

Sure. When you tip the air stream, the ball begins to exert a normal force on the dynamic pressure wall by Fn = mgcos(angle). When the normal force exceeds the dynamic pressure, the ball falls.

Flow in a straight pipe will have a certain pressure drop depending upon the pipe material and flow etc. When the flow in a pipe goes through a bend there will be a drop in the static pressure. Dented pipe is likewise a flow disturbance and will result in some static pressure drop.

Viscosity is a fluid property characterized by its resistance to flow. Non-Newtonian fluids are a special property of viscosity. Fluids such as peanut butter and tooth paste are non-Newtonian fluids.  They can form pointed surfaces. Fluids such as water and air which flow “normally”  (Newtonian fluids) do not form pointed surfaces. That point is a singularity that when differentiated may appear to give an infinite viscosity.

well, others might have told you it is pressure, and actually even i would have gone for it!\nbut since you have mentioned in particular on a fluid, then this ratio can also be called as Bulk's modulus(though this applies even to solids)\nit can also be the coeff of viscosity taken velocity gradient times\nthere can be various other depictions also

It should crumple up when the water cools down. This is because the air trapped in the bottle undergoes contraction upon cooling, and in the absene of extra gas filling up the space left behind, the walls of the bottles are forced inwards, thus deforming them.

In the steady state, water flows out of the aqueduct, leaving the force on the floor&walls unchanged. However, then the barge is first introduced, the displaced water flows as a wave, causing greater forces near the wave-front.

Its more like filling a plastic bottle with water and squeezing. you get a 'Fountain' of water and then some trickling over the side.

When you put water in a beaker or test tube, you see a curved surface. With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. this is what is called miniscus.\n\nA few liquids have a "backwards" meniscus. An example is mercury. If you put mercury in a test tube, it would be higher in the middle than at the edges.

max flow against min. head , and visa versa , exceeding the pressure it can give , then the flow will go to zero
