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.

Mgh 1 2mv 2 mass of the water doesn t matter here as it cancels out. 1 kpa 1 000 pa 1. What water height value corresponds to a pressure of 1 mpa. What water height value corresponds to a pressure of 1 kpa.

This will give a discharge of a foot for the waterfall. 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. 02 10 4 0. For example if your fountain is 30 inches tall find a pump with a maximum lift of 45 inches or more.

First i calculated the speed of the water. The second way is the pragmatic way. 1 mpa 1000 000 pa 1. So we can calculate the water s velocity using conservation of energy.

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. To create a simple waterfall the gallon per hour that churns from the pump should be 1 500. 02 10 4 102 m w c. Any horizontal diagonal flow is then measured by its length and 1 of head added per 10 of horizontal diagonal distance.

I estimated the height that it reached after shooting out from the fountain to be roughly 10cm. A ratio of 0 7. The top height the pond fountain pump can lift the water up to is called maximum head or max head. Then multiply the result by 7 47 to get the number of gallons.

The head is measured straight up from the water level of the pond. Keep in mind that the larger a fountain is the heavier it will be. In his book the hot garden scott calhoun suggests that a fountain should never be taller than 1 3 the height of your home. A waterfall provides a dramatic aesthetic to the landscaping that buttresses a home.

Choose a pump that is at least one and one half times the head height for optimal performance.
