Water fountain can also be used as a bathing fountain intended for people to cool off in. You don't need our permission to copy the article; just include a link/reference back to this page. A small water pump (less than 100 gallons per hour) and clear plastic tubing (1/2" inner dimension or 5/8" outer dimension). The effect of sunlight was the main concern regarding the structural aspect of the Persian garden design. While covering the pump with rocks is not really necessary, it does make it easier to conserve room in a small container and helps muffle any humming noise. Cleaning the pump: Pump do need cleaning occasionally. Once the pump is in place, put some water into the container and make sure the pump is working. We used the same under-the-bed tub that we used for our Ocean Science Experiments. After the flow control valve a long hosepipe was connected and through it the water goes to the fountain. Cut a final length of tubing and insert this into the second hole, pushing it in almost to the bottom of the container. If you are using a pump with a regulator, you may want to see what the different settings will do. Campus is also under-equipped for students seeking to conveniently refill their reusable water containers. to remove any slime and algae. Heres a really interesting YouTube video that explains how water towers and city water delivery work. A suction pipe was connected to the pump at its inlet port. Bringing bubbling, flowing water into our living and working areas helps bring a natural feeling back into our lives. Its important to plan a water fountain properly. The pump was set to draw water from a reservoir. Through our primary surveying as a committee, we have heard much in the way of student support for a greater number of water bottle filling stations in main buildings on campus. freeiconspng This project also includes the participation of the Students for Environmental Concerns (SECS) RSO. We wish to express our respect and gratitude to our supervisor to give us the opportunity of executing such a wonderful project. This will become the air supply container and must be the lowest part of the apparatus. When the roots get too big, replace it with another plant. To straighten the hose, boil it in water for a while. In this experiment, were going to make a working water fountain with a 2 liter soda bottle and some simple supplies from around the house. Submersible pumps are made for safe, quiet operation underwater. The fountain supply container must be higher than the air supply container. You can add a small amount of bleach to the water to cleanse the fountain. Place it at the end of a walk or at the side of a patio or courtyard garden. Until recently, water gardens were beyond the reach of many gardeners. While we are at it, insert fertilizer tablets, about one per five quarts, into their containers. This is available in spray cans and is used for insulation. The pump should ideally have suction cup feet to hold the pump securely on the bottom of the container, a quiet motor, simple maintenance, and an output of less than 100 gallons per hour. In most cases, a water feature should function as an accent-not a focal point. The water has to cover the pump; otherwise, the pump will burn out. Take your second container and make two holes through the lid of this one. At the upper stage of the fountain the shape of the jet was not so uniform. If we are thinking about a spray fountain, it should be placed in a location protected from wind. One of the projects which our committee has been discussing since the beginning of the semester has been encouraging the student body to wean off of disposable water bottles and promoting reusable water bottles, with the greater goal of curbing litter and wasteful discarding of recyclable bottling materials. During the execution of the project we have learnt a lot about the components and accessories of a water fountain such as supply pumps, piping system, flow control device, fountain nozzles, fountain materials etc. Currently, the Illini Union has a variety of water fountains in the facility, totaling 16 units. If you make one, why not film it and upload it to YouTube - you never know; we might just decide to feature it here! This water fountain science experiment is fun for preschoolers all the way up through middle schoolers. Water fountain may be of various kinds- fountains may be wall fountains or free-standing. As a decorative addition to the window garden or merely a wall piece of modern art, the sound and sight of running water is very delightful. dubai fountain water bellagio largest building Some plastic pots tend to vibrate when you put everything together. Edible Science for Kids. The nozzle could not be adjusted with the PVC pipes concentrically with uniform clearance which causes the non-uniformity of shape. Insufficient size and depth mean you'll have to fill the fountain more often. We added a separate container to be our building. Click (or touch) and drag to pan; scroll (or pinch) to zoom. Rocks; pebbles; slate; crystals; semi-precious stones; drift wood pieces; shells. the kids are excited to have me come because we DO something not just talk or sit at a desk. However, this is not the case and, as the air supply flask fills with water, the jet of water from the nozzle will decrease in power and stop altogether. If you are using a pump with a regulator, you may want to see what the different settings will do. The constructed fountain is situated in front of the EME building of BUET. the height of the highest point of the water is to be pumped over the water surface of the reservoir pool. Historians are almost certain that Heron (c. 10 CE - c. 70 CE) taught at the great university of Alexandria, Egypt, and used many of his inventions as teaching aids. The great Greek inventor, Heron of Alexandria (sometimes called Hero) created this device as one of his wonderful ways of showing students how the underlying physical and mathematical principles worked. For a formal garden, we may want a classic standing fountain. aquascapes If, on the other hand, our yard is composed of mixed borders and naturalistic plantings, a formal water garden would look out of place. This means you're free to copy, share and adapt any parts (or all) of the text in the article, as long as you give appropriate credit and provide a link/reference to this page. At the delivery port of the pump a flow control valve was connected. Don't have time for it all now? At the lower stage of nozzle the flow was of required shape. You must have JavaScript enabled to use this form. So if you want to have a slow moving fountain that doesn't splash out all over the place, a 5/8" outer dimension hole and tubing can be used. If we keep our yard neatly mowed, if shrubs and hedges are carefully trimmed, and other plantings are in formal beds, a geometric pond will suit it perfectly. We should avoid placing a pond beneath the trees because it will fill with leaves and debris. The most common tubing size is 1/2 inner diameter, 5/8 outer diameter. Your basin will need to be raised, as it must be higher than the two bottles. :). Different types of water fountains are splash fountain, Spray fountains, fountains for drinking water, animated fountain etc. Fit the clear plastic tubing on the pump spout and get about 8 of the tubing to elevate the water. Plug the pump into the electrical outlet. Different shape of fountain under different flow rate: Table-5.1.1:Calculation of flow rate for fully opened valve-, Inner diameter of 1st pipe : 19.2mm, Outer diameter of 1st pipe : 26.0mm, Length of first pipe : 1.08m, Inner diameter of 2nd pipe : 34.2mm, Outer diameter of 2nd pipe : 41.2mm, Length of 2nd pipe : 0.87m, Inner diameter of 3rd pipe : 51.7mm, Outer diameter of 3rd pipe : 60.0mm, Length of 3 rd pipe : 0.7m, Thickness of 1st pipe : 3.4mm, Thickness of 2nd pipe : 3.5mm, Thickness of 3rd pipe : 4.2mm, Distance between 1st & 2nd stage : 200mm, Distance between 2nd & 3rd stage : 180mm, Height of 3rd stage : 700mm, Length of hose pipe : 9.3metre, Diameter of hose pipe : 34mm, Length of short PVC pipe : 0.38m, connected to fountain : 0.15m, connected to pump :1.22m, Gate valve(Fully open) : 0.15, Length of suction pipe(PVC),Ls : 1.93m, Diameter of suction pipe,Ds : 0.026m, Length of short CI pipe : 0.254m, Of check valve : 0.5, Mass flow rate, m= 1.174 kg/s, Density of water, = 997 kg/m3, Volume flow rate, Q=m/, Viscosity of water at room temp, = 8.910-4 Nsm-2, Reynolds number, Re=dv/, Using Reynolds number and relative roughness of pipe, we get from Moody diagram, Loss in PVC pipe, h1 =fLV2/2gD, Check valve & bend loss, h2= (k1+k2)v2/2g, Loss in cast iron pipe, h3 = fLV2/2gD, Total loss in suction side =0.2424m+0.25m+0.0877m, Head loss in CI pipe, h1 = fLV2/2gD, Loss in T-joint & Gate valve, h2 = (k1+k2)V2/2g, Cross sectional area of hose pipe A=d2/4, Velocity through hose pipe = (1.1810-3)/(9.110-4) m/s, Using Reynolds number & relative roughness of hose pipe, we get from Moody diagram, f=0.04, Now, Loss in hose pipe, h3 = fLV2/2gD, Loss in short PVC pipe, h4 = fLV2/2gD, Loss in 1st pipe(inner), h5= flv2/2gd, = ( 0.013 1.082.222)/(29.81 0.019) m, Flow rate through 2nd stage, Q2= (A2-A1)v2, Loss in 2nd stage pipe, h6= flv2/2g(d2-d1), = (0.0130.872.222)/(29.81 (0.0342-0.019)) m, Flow rate through 3rd stage, Q3= (A3-A2)v3, Loss in 3rd stage pipe, h7= flv2/2g(d3-d2), = (0.0130.72.222)/(29.81 (0.0517-0.042)) m, Total loss in delivery side = h1+h2+h3+h4+h5+h6+h7, = (0.43+0.55+0.9424+0.477+0.1822+0.1869+0.24) m, Total head, H = Suction head+ Delivery head+ Losses+ Velocity head at exit, = (1.93+0.254)+(0.62+0.7+0.18+0.2)+(0.58+2.9792) + (2.222)/(29.81)3, 5.3 Variation of water flow with the annular gap of three stages, Table: Calculation of 1st stage flow when annular gap is 4mm. Add moss and foliage as desired. Plug an electric pump into a ground-fault circuit interrupter, which may need to be installed by a licensed electrician. The basic idea of creating a fountain is visualizing how the water flows and bubbles through and around rocks, wood, and whatever else you choose in a way that sounds natural and looks pleasing. Although many fountains were not designed as bathing fountains, children of all ages often use them for that purpose. Or you can substitute polyethylene spray foam for the bulk of the rocks. Balloon we used a 9 inch balloon, but a smaller one will also work, Drill or something to make a hole in the plastic bottle. A pump should be submerged in a stone bowl and a hidden tube may be used to connect it to a hollow bamboo pole. The smaller the tubing, the stronger the water pressure. Its such a fun project, and you can make it work over and over again. Pool depth is also a consideration. This experiment allows children to see that air takes up room and is always present even though we can't see it. Two pumps were connected parallely and using a T-joint flow was delivered. The water fountain created by us was of three stages. You could even extend as far as having them write a report on it or write it up properly with a hypothesis etc. And heres another awesome way to demonstrate that Air Takes Up Space. Ultimately, because of the the universitys standing among other institutions, we have a unique responsibility to adopt this project. Check out the Instagram page for a list of all the blog posts that have been featured on Instagram. Little kids will think its a blast! The objective of our project was to design a unique shape of staged water fountain that would add to the variety of choice for the people. Any dead leaves and other organic material that has accumulated on the pool bottom should be removed. The attached file is the final report for the Water Bottle filler retrofit program. Make sure that the seal around the tube is airtight, using the silicone sealant.
