A bucket, a measuring cup, and a stopwatch is all you need.\n\nOpen the tap until it has achieved a steady flow, then put the bucket under it while turning on the stopwatch.\n\nFill the bucket to a desired amount or until you have a fairly long time.\n\nMeasure the water in the bucket and divide it by time. Thats the volume flow rate.\n\nTo get the velocity of the water when it exits the tap, divide the volume flow rate you have computed above with the area of the (circulare) hole.

If the pressure's the same, then the change in volume would be "(3.61*A*X)/SQRT(Y) Where: A = Cross-sectional area of discharge\npipe in square inches\nX = Horizontal distances in inches\nY = Vertical distances in inches"

Dear Asker!\nfirst you have to know equilibrum between income and outgoing flow. \nSecond if we have equilibrum , we must evaluate if the flow is taking the shorter way or is expanding all the cross section of the reservoir. If the second is right ( which is not fully right) it could be calculated easely. \nso, residence time is T=V(volume)/P(income flow or outgoing flow)

The measurement of a river’s meander is quantified with a value known as sinuosity index. For single channel rivers, excluding braided channels, this is defined as :\n\nSI = length of channel axis/length of meander belt axis\n\nThis sinuosity index has been used to separate single channel rivers into three general classes: straight (SI < 1.05), sinuous (SI 1.05-1.5), and meandering (SI > 1.5)\n\nGenerally as gradient decreases, the sinuosity index increases.  To say that meandering causes changes in gradient would be misleading. The overall channel pattern is a response by the river to balance its energy expenditures as it carries load and discharge. The river’s tendency to meander is related to its discharge, and its type and amount of sediment load as well as the gradient.\n\nWavelength and amplitude of river meanders are not random. They are controlled by aspects of overall load, discharge, and gradient. In addition to lateral migration of channels, there is a long-channel variation that forms patterns of riffles and pools.  These riffle-pool patterns  which are related to flow cells tend to initiate bank erosion and develop meander bends.\n\nMount, Jeffrey F. 1995\n“California Rivers and Streams:  The Conflict Between Fluvial Process and Land Use”\n\n\nI’m a geologist.

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.

If you're referring to a reverse flow due to natural OR artificial causes, the most noteworthy is the North fork of the South Branch of the Chicago River. This was reversed to have sewage flow down the Great Lakes/Mississippi waterway. The North Branch and South Fork of the South Branch were unaffected.\n\nSpeaking only of natural phenomena, there would, I am sure, be many. One I know of for sure is the Mekong, which is so close to sea level that the twice daily tides cause it to reverse flow and actually flow backward in some areas.

Let \nQ = volume flow rate in Litre/sec, \nD = diameter of the nozzle in cm and \nV = velocity of water in metre/sec. \n\nThen,  V = (40*Q)/ [pi*(D^2)]\n\nwhere pi = 3.14

Fresh water evaporates faster than the solutions will.  Between the solutions it would depend on the number of particles dissolved in the water.

The water comes from a point elevated far above the sink height (a reservoir in upstate NY).\n\nBecause its source is higher, the water will flow (downward)--even though the pipes might go 'up' a buiding. Its all about the conservation of energy laws you can learn about in physics.\n\nFrom the reservoir it is piped to the city, and it gets filtered and treated before it gets to the sink.\n\nThe sink valves hold it back until you open them, and let the force of the flow down your drain, where it goes out to the river.

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 winding nature of many river channels is called meandering, also referred to as sinuosity. The sinuosity of a river is not just the result of water taking the easiest path. There are many internal and external factors that determine the overall channel pattern. To some extent there is still debate within the science about what factors are most important.  There are mathematical formulas that can be used to compare different rivers, but they are not quite good enough to actually explain all the variables yet. \n\nIf you look at a map you will see that the sinuosity of a river has a predictable wavelength (length of a full turn) and amplitude (width of a meander across the river flood plain), so it is clearly not a random process. One useful formula that relates the bankfull discharge of a river to its meander wavelength is the following:\n\nLength of meander=L\nBankfull discharge (volume of the river)= Qb\n\nL=54.3 (square root of Qb)\n\nThe factors that affect the size of meanders that are external to the river are things like the type and density of vegetation along the river bank, the type of material in the river bed and bank, the overall volume and variability of the river volume, and the overall gradient of the river. The higher the gradient the less likely a river will meander. Rivers that meander widely are typically flowing across a river-deposited flood plain of sand, silt and clay materials, but because these materials are not always deposited evenly the inconsistency will affect the river channel migration. Along many meandering rivers there are forests growing, and as trees fall into the rivers they can have major effects on the current flow.  \n\nThe internal factors probably have much more to do with the strong tendency of rivers to meander (at least that is my opinion) and create the regularity of meanders. Small oscillations within flowing water creates alternating bed profiles along the length of most rivers. These alternating bed profiles correspond to higher and lower gradients resulting in faster and slower speeds of flow.  These two bed profiles are known as riffles and pools. The riffles are typically spaced about 5-7 times the width of the river apart, along the length of the river and usually have bottom sediments of the largest size found in the river (more gravel, cobbles, etc). Turbulence in the river created by these variations in the bottom of the river creates cyclone-like spirals of water that will both erode the bottoms of pools and when they diverge they will build bars and riffles in the middle of the channel. \n\nThis internal turbulence also causes bank erosion, and once it begins it is self-perpetuating. As the meander begins to form, the water moving along the outside of the meander actually piles up, causing more bank erosion, and the higher speed of the water along the outside of the meander also allows the water to erode and carry more material. Meanwhile, the inside of the meander is the slowest moving water and will deposit material, building a sand bar, also called a point bar.\n\nThe meanders eventually reach a limit of size (amplitude) either when they encounter the edge of the flood plain and bedrock, or when they get so wide they begin to intersect each other. As this happens the river will cut them off forming an oxbow. Other times at flood stage a river will scour away the point bars and abandon its own meanders until flow returns to normal and the process of building meanders starts anew. \n\nHere is a good resource with some illustrations of the process:\nhttp://www.ucpress.edu/books/pages/6664/6664.ch04.html

This all depends on the diameter of the second pipe, if you reduce the diameter then the pressure in the second pipe will increase. i.e. psi. to make sure you got the same flow rate then you will need to know the orginal flow rate. and the flow rate of the second pipe. then you can get it balanced out, by reformulating the psi equation/ the flow rate for both pipes.

I believe in a generalized fashion the equation for flow rate is:\n\nFlowrate = K*(cv)*((p)^.5)\n\nK = a variable to adjust for various fluids

When you put an object in water--or any other fluid that is minimally compressable, like milk or oil or alcohol--the object takes up space.  Especially for fluids that are very runny--like water, in contrast to, say, old crank-case oil--the fluid will fill every nook and cranny available.  Since the water, or other non-compressable fluid, has to move out of the way for the object put in it, the apparent rise in the total volume of water-plus-object is due to the volume of the object.\n\nOf course, if the object FLOATS in water, you're in a whole new situation: the object will displace (move aside) exactly the amount of water that weighs what the object does.  That's a whole different discussion!

It depends on the pressure and temperature of the water so the previous answer is limited to only one condition.
