how do you measure the speed of water through a hose?

speed is distance divided by time. So work out the distance the water needs to travel and divide by the time taken. Add more details if you want to know a more complex way to work out the speed.

several ways to measure volume.\nfor a liquid you can use a graduated cylinder and measure the volume in milliliters, liters or some similar unit.\nfor a reqular shaped solid you can calculate the volume by measuring the dimensions.\nfor a strange shaped solid you can submerge it in water and measure the difference before and after. Archimedes figured that one out about 2000 yrs ago.

Set the string vibrating. Use a variable frequency xenon lamp, and keep changing the rate until the string appears to be a static wave. Then you know the frequency of vibration. At this stage you can also measure the wavelength of the vibration. The velocity is then wavelength*frequency.

If you want to carry a higher volume of water, use the 3/4" hose. If you want a higher velocity of water, use the 5/8" hose.

You need to know the velocity of the air entering the pipe.  In your case that will depend on the speed of your vehicle.  \n\ncfm= cubic feet per min  (strange units given that your pipe is metric)\nradius of pipe = 36mm / 2 = 7.0866 in\nArea of the crosssection of the pipe is: 3.1415 x (7.0866)^2 = 157.8 in^2 = 1.0956 ft^2\n\nFlow of air into pipe, Q = 1.0956 ft^2 * velocity of air entering pipe in ft/min = Q in cfm\n\nvelocity of air entering pipe is probably the same as the velocity of your car.

well, if it is steady flow and incompressible, then the flow rate doesnt matter (cuz equal volume of water flows in as the amount that flows out so no change in volume). so the diameter of the pipe is 10" so the radius is 5" and you can find the area by doing A=pi r^2. and then 1 foot is 12 inches so then multiply that by 12 to get the volume in um inch^3. so its 300pi"^3. hope that helps.

Well....moving water has a different refractive index to still water. So if you can monitor the intensity of color using the color of the light from still water you will see a change in the color when the water is moving. It is then possible to see that movement in the water is taking place. \nThe speed of movement maybe be also indexed as a change in refractive index. \nSo, it would be possible to run some controlled experiments and determine convection of water in some form of useful units.

Here's the best site I have found for calculating the velocity of the spud:\nhttp://ffden-2.phys.uaf.edu/211.fall2000.web.projects/J.%20Jones%20and%20T.%20Kenny/Projectile.htm\n\nThis is for a combustible firing chamber.  The pneumatic guns are more predictable and reliable since the pressure can be set prior to firing.  Where the combustible require calculating the air to fuel mixture based on the size of the firing chamber.  This is explained on another part of the site referenced above.\n\nThe best choice for this type of gun seems to the the solenoid valves that are common on sprinkler systems.\n\nThey also recommend that the barrel resistance be measured using a simple fish scale to find the force of resistance of the spud against the barrel.\n\nI also looked at a rifled barrel that provides better accuracy.\n\nMost spud gunners use parametric measurements to find the range of their cannon.  This is done using inclimeters for altitude and pressure gages to measure the max pressure in the firing chamber, while increasing the amount of fuel or air pressure and taking a series of measurements to find the characteristics of the cannon.\n\nenjoy\n\nj

crudley you could say pressure = force/area so re arrange. if you know the presssure of the washer and you measure the area of coverage of the water then you could get a very rough estimate.

A water gauge would have been used. A hosepipe fitted both ends with glass rod, filled with coloured water, and of course it would be level

if the question is: If it takes 3 hours to travel 24 miles downstream and 6 hours to travel UPstream, how fast is the current? then,\nlets call the travelling speed Vt and the current speed Vc\ndownstream we have Vt+Vc=24miles/3hours=8mph\nupstream we have Vt-Vc=24/6=4mph\nto solve the system of two equations we can add the equations and get 2Vt=12, Vt=6mph\nVc=8-6=6-4=2mph\nThe current is 2mph fast.

stick it in a tank of water then measure the water displaced.archemedes law

measure the size of bowl(better if rectagular or square) and time how long it takes for waves to hit the sides for one minutes. about 10 waves. multiply by 60 to get speed/hr

measuring device of some sort (scale, ruler, thermometer)

Yes, it is possible to find pressure drop per unit length from  some more information about density and viscosity of the fluid and roughness of the pipe. Any book on fluid dynamics gives the procedure.\n\nTheformula is:\nPr head = 2f(v^2/g)(N/D)\nwhere \nf= friction factor (generally found from a chart)\nv= average velocity of fluid \ng= conversion factor (having magnitude equal to std accln due to gravity)\nN= Equivaalent length\nD= diameter of pipe.\nYou have to follow some standard system to work out this problem (see standard reference)

just measure how much water they lose to the atmosophere some how and keep track of the amount of water you have added over a period of time. \nThis should be an interseting experiment.
