 | Irrigation Plan Reading | | |
Problem 4.02 - Irrigation Plan Reading You are given an irrigation landscape plan showing some of the details in a residential yard. It is inefficient to keep going back for additional materials, so your employer has put you in charge of calculating the materials needed for this job. First, you need to be familiar with the scale on the plan and using an architect scale. Incorrect use of the architect scale will result in major errors, so be very careful. Reading the North arrow is also important. You will be required to do some simple counting of items on the plan, but study the plan carefully to make sure you have counted them all. You are also required to calculate GPM for one zone. A formula is provided for you to calculate precipitation rate. All you need to do is calculate the area using your scale and add up the GPM for each nozzle in that zone. Return to "About the Exam"
