How to calculate the water flow rate of your misting system?


Now that you are making an optimum use of your outdoor space with a misting system and wanted to know the water flow rate of the system, it may be easier said than done, but not really! You should be calculating as gallons per minute (GPM). By dividing the number by go you can convert the gallons per hour into gallons per minute. While there are several other factors that will help you find out the water flow rate exactly, the number of misting nozzles you can use per zone is one of the most decisive factors. More often than not, given as gallons per minute (GPM) or gallons per hour (GPH), at any given time, the amount of water flow through your water pipes is called the flow rate. Compared to smaller pipes, larger pipes can let more water to pass through. However, a mixture of large and small pipes are used at homes, hence an accurate test at the spigot is considered necessary. You will have to find out how much water can pass through your outside valve that will be supplying the water to your outdoor misting system. Given that all misting nozzles are designed to deliver a given amount of water, you need to find out how much water your valve can supply to settle on how many mist nozzles can be used.

To come up with an accurate water flow you need to find a bucket that will hold one gallon of water and then when you are done, add one gallon of water to it. Make use of a milk container, as it helps find out the accurate gallon. Simply fill and transfer the water to the bucket. Mark the one gallon from the inside of the bucket. Toss out the water and hold the bucket lower than your outer surface valve. You will be opening the valve i.e. the spigot on all the counts and point in time how many seconds it takes to fill the bucket to the gallon mark. To determine the flow rate in gallons per minute, divide the number of seconds into 60. Have a note of the flow numbers down and in case if you have figured gallons per hour, divide the number by 60 to convert it to GPM. Typically, a ¾- inch hose can distribute 23 gallons of water per minute, on the other hand, a hose that is of 5/8- inch can allow 17 gallons per minute. Find out your hose size and while also determining the flow of your garden hose. In order to determine the flow rate, examine the water delivery piping of your misting system and use the piping size chart.

When you are done calculating and making a note of all the numbers, here's how to determine how many misting nozzles we can use per zone on our misting system:

  • The flow of your spigot, garden hose and water piping Gallon per Minute (GPM) of your misting system should be compared overall.
  • misting fans
  • In order to find out the maximum flow in GPM, choose the lowest of the numbers.
  • Now make use of this number to decide how many misting nozzles can be used per misting zone.
  • Find the flow rate of your misting nozzles. Depending upon the nozzle type you will have to make use of that particular mist nozzle chart. If in case you are using misting nozzles from a different manufacturer, then you will have to refer the manual that came with the nozzles, you can also Google search for the information, or call up the help center of that particular manufacturer in order to calculate the flow rate.
  • Referring the chart, find the flow rate of the mist nozzle you are using.
  • Given that the charts give the flow in gallons per minute (GPM). Divide the number of 60, if your nozzle flow is given in GPH.
  • Now you should take the lowest flow number that you determined earlier and divide it by the flow of a single misting nozzle.
The answer i.e. the resulting number is the highest number of misting nozzles you can use per zone.
