Calculate Volume Flow & Distance of Sprinkler Holes | DIY Garden Project

[Pau Hernandez]

Hello,

I do want to make a small sprinkler for my garden. As you can see it is a simple tube with one end sealed and the other end will be attached to the water hose. Now what I want to do is drill a couple holes to the sides of the tube and get a sprinkler like that. I would like to know how to calculate the volume flow through each hole and how far the water ray will shoot out of the tube. My logic says is that the first hole will get most of the water and with each hole the water ray will be weaker.

Here is a small drawing:

My logic says is that the first hole will get most of the water and with each hole the water ray will be weaker.

Not necessarily so that the last hole is a dribble.
Otherwise boom sprayers would not function as demanded.

Washington State University's website has a nice collection of agricultural irrigation calculators for a starting point. Take a look here: http://irrigation.wsu.edu/Content/Select-Calculators.php
