Water Fountain Height Calculation

Otherwise calculate the volume by measuring the length width and depth of the pond in feet and multiplying these numbers together.

Water fountain height calculation.

Use a rule of thumb to choose a pump size and thus water volume per second divide by the nozzle area to figure out the initial velocity upwards calculate the height the water would rise to given no air drag nor interference from falling water and then reduce by some inefficiency parameter e g. I estimated the height that it reached after shooting out from the fountain to be roughly 10cm. He also reminds readers that a fountain that is deeper than it is wide will help conserve water because there is less chance for evaporation. Mgh 1 2mv 2 mass of the water doesn t matter here as it cancels out.

For example if your fountain is 30 inches tall find a pump with a maximum lift of 45 inches or more. This will give a discharge of a foot for the waterfall. 02 10 4 0. The head is measured straight up from the water level of the pond.

What water height value corresponds to a pressure of 1 kpa. A waterfall provides a dramatic aesthetic to the landscaping that buttresses a home. The top height the pond fountain pump can lift the water up to is called maximum head or max head. Choose a pump that is at least one and one half times the head height for optimal performance.

Keep in mind that the larger a fountain is the heavier it will be. 1 kpa 1 000 pa 1. So we can calculate the water s velocity using conservation of energy. In summary the variables in bernoulli s equation are as follows.

First i calculated the speed of the water. 02 10 4 102 m w c. 1 mpa 1000 000 pa 1. H maximum height obtained by a vertical fountain h 0 starting firing height h v2 0 2g theoretical maximum height without drag or breakup that can be obtained by a vertical foun tain m d droplet mass pr ld3 6 for spherical droplets r horizontal range r max h0 0 v 2 0 g theoretical maximum horizontal range with.

To create a simple waterfall the gallon per hour that churns from the pump should be 1 500. Any horizontal diagonal flow is then measured by its length and 1 of head added per 10 of horizontal diagonal distance. A ratio of 0 7. The second way is the pragmatic way.

Then multiply the result by 7 47 to get the number of gallons.
