Laminar Flow & Turbulent Flow?
925359
Laminar implies smooth and in layers.  Turbulence suggests swirly and mixed up.  Water flowing slowly out of a hose lying on the ground exhibits mostly laminar flow.  If you turn the faucet on full blast the flow will become turbulent.   Mixing two liquids is more efficent if you mix vigorously.  Simply stirring is not efficient since the flow is laminar.  You get the idea.

both.  the friction, as well as creating its own heat, slows the airflow, which aggrivates the compression along the leading edges.\n\nI'm pretty sure.  don't put this on a physics test and then blame me.

Aplly the following formula:\n\nG = w * A, where:\n\nG - flow rate [m^3/s]\nw - speed of fluid [m/s]\nA - transversal section area of the pipe [m^2]

This happens because the flow gets faster because of acceleration due to gravity. The flow (volume/time) must keep constant on every section (conservation of mass), so the only way this can happen between points that have different velocities, is that the cross section of the flow gets smaller as speed increases \n\nMass conservation:\nArea1 x velocity1 = Area2 x velocity2\nBecause of gravity, velocity1 < velocity2.\nSo Area1 > Area2

I agree that I believe this to be a heat transfer equation however it seems that something is missing.  From the gut I would think that it is a way to calculate heat loss through something like a double-paned window.

the first link explains system boundary and the second is an explanation of computer simulations in the context of "conceptualizing a system".  hope this helps

Heat transfer is proportional to the temperature difference between the two objects, in this case the temperature difference between the walls of the vessel and the fluid in contact with the walls. Stirring brings colder fluid in contact with the hot wall of the vessel. With stirring, the temperature difference is greater between the hot wall of the vessel and the colder fluid, so heat transfer is more rapid.

In general resistance increases.If there is no turbulence then it can be shown that viscous drag on a spherical moving body of radius r and velocity v is \n6*pi*(eta)*r*v\nwhere eta is coefficient of viscosity.\nTherefore air resistance is usually taken as directly proportional to velocity.\nHowever in real life things are not that simple.With turbulence various other forces come in play.Surprisingly it can reduce the air drag too.Though it may cause deviations in path as forces are no longer just opposite to velocity .

The phrasing is wierd, shouldn't there be a from between flow and the?\n\nIf two substances have different _temperatures_, heat will flow [from] the hotter [substance] to the colder [substance].\n\nThis is because heat, at the molecular level, is related to how fast molecules are moving. When a substance whose molecules are moving faster comes in contact with an object that's moving slower, the faster molecules will collide with the slower molecules of the second object, slowing down the faster molecules while speeding up the slower ones. Thus, heat (average kinetic energy of a substance) is transferred from the hotter substance to the colder one.

Your problem can not be solved accurately unless you also state the length and roughness of the pipe.  Picture two pipes, one ten feet long and the other the length of a football field.  Clearly the longer pipe will greatly resist flow.  Also a smooth copper pipe will resist flow less than a rusty rough one.  The Crane company published a book that can be used to estimate flow through pipes based on lab tests.  Good luck.

Well there are a couple of forces to consider. Gravity determines that no matter what the weight of the object speed should be the same, but we know that doesn't always happen. That's because in this case some a major variable is set. The viscosity of the blood is probably much higher then the normal saline. In determining flow through a pipe the cross sectional diameter, and resistance secondary to viscosity are the main contributing forces. Assuming equal amount of starting solution, and exactly the same lines to flow through, the more viscous liquid will flow slower due to turbulence from decreased laminar flow. Of course you also have to consider if any external forces being put on the iv bags such as; air pressure, pressure from the iv bag being shaped differently, and not to forget that nothing is ever made the same...including iv lines. Anyway there are a lot of different variables contributing to your problem, but scientifically the main contributing factor in your case is probably is viscosity.

its basically how u see the question.\nin fluid dynamics, eq of continuity specifies that a*v = constant so with inc in area, velocity decreases,hence pressure increses\n\nwhile in solids, the case is not the same , pressure = force/area hence assuming force constant with inc in area, pressure must dec

Most fluid flow handbooks have this information. The Foxboro company use to have the very best manual for this.You might find one on ebay. Many thermodynamics text books also have this information.

You could use Bernoulli's equation between two points to solve for the velocity of the fluid in question.  Area of the pipe (or area of the cross section of what the fluid is flowing through) multiplied by the velocity will give you the discharge.  If you aren't familiar with Bernoulli's equation, see the source below.

From what I recall, the flow rate (GPM) would be the same throughout the pipe.  The equation of continuity for incompressible fluid flow is\n\nA(1)*V(1)=A(2)*V(2)\n\nwhere A is the cross sectional area and V is the velocity of the water (1 and 2 are the before and after positions).  Looking at this, the only thing the different diameter pipes (and thus the CSA) affects is the velocity of the fluid.  When you have a reduction in CSA, the velocity increases (if you partially cover a garden hose, the water shoots out faster), but you're still getting the same amount of fluid out per time unit.\n\nTry this - time how long it takes to fill a cup using your kitchen faucet.  Then, fill the same cup, but cover your faucet like you would a garden hose so that the water shoots out faster, and time that fill.  The times should be the same, plus or minus timing errors.

The loss of head in a pipe is just another way of saying that you have lost pressure in the pipe.  This could affect the type of flow regime in the pipe, for example the fluid could go from turbulent flow to laminar flow.  With the loss of pressure there will be an accompanying loss of flow volume.
