Efficiency Saves Money!
This page is designed around calculations I use to perform an irrigation audit. This is simply to give you a guideline for water usage and is by no means perfect.
Enter the throat area in square inches for your catch cups. This allows you to use any size container measuring less than 12 inches across as long as you know the throat area in square inches (opening through which the water enters). You will also need a way to measure the volume in milliliters. There are specially designed catch cups for this purpose, as seen in the picture.
This is one of the least expensive catchcups available.
