Watering and Irrigation
Catch Can Uniformity Calculator
Calculate lower-quarter irrigation distribution uniformity. The form keeps the source measurements beside the calculated distribution uniformity.
Enter values for distribution uniformity
Catch Can Uniformity needs lowest-quarter average and overall average from one case.
Catch Can Uniformity field limitation
Enough catch cans are needed to represent the full zone. Continue with Hose Watering Time Calculator to estimate hose operating time from measured flow and target volume.
A zero Overall average leaves distribution uniformity undefined in Catch Can Uniformity.
Purpose of the distribution uniformity estimate
Calculate lower-quarter irrigation distribution uniformity. Catch Can Uniformity limits that task to Lowest-quarter average and Overall average.
Save Distribution uniformity with the Catch Can Uniformity units and scenario name.
From lowest-quarter average to distribution uniformity
Catch Can Uniformity compares Lowest-quarter average and Overall average and reports the relationship as a percentage.
Catch Can Uniformity evaluates lowest-quarter average at 0.28 in and overall average at 0.4 in as 70.00%.
Interpreting this distribution uniformity value
Catch Can Uniformity summarizes its formula as Distribution uniformity.
Input definitions for distribution uniformity
Distribution uniformity is calculated from Lowest-quarter average and Overall average. Check the Catch Can Uniformity units before editing.
Lowest-quarter average. The Catch Can Uniformity assumption is 0.28 in; note the source of any replacement.
Overall average. The Catch Can Uniformity assumption is 0.4 in; note the source of any replacement.
Lowest-quarter average source record
Write down Lowest-quarter average and Overall average before acting on Distribution uniformity.
The Catch Can Uniformity note should distinguish direct observations from rates, forecasts, targets, and other assumptions.
Once an actual outcome is available, enter it separately using the same definition as distribution uniformity.
Reproducing distribution uniformity
A second person should be able to reproduce distribution uniformity from the Catch Can Uniformity notes.
Keep the first lowest-quarter average value when creating a revised scenario.
Catch Can Uniformity low-and-high comparison
In a Catch Can Uniformity sensitivity check, compare lowest-quarter average at 0.28 in and 0.308 in. Distribution uniformity evaluates to 70.00% and 77.00%, respectively.
Both cases hold overall average unchanged; preserve the other Catch Can Uniformity inputs too.
Prefer measured lowest-quarter average ranges in Catch Can Uniformity.
Common questions about lowest-quarter average
Can Overall average be zero in Catch Can Uniformity?
In Catch Can Uniformity, zero overall average makes distribution uniformity undefined.
Can a nominal device rate replace measurements in Catch Can Uniformity?
No. Check actual delivery under operating pressure because clogging, elevation, and zone size can change distribution uniformity.
How does “Enough catch cans are needed to represent the full zone.” affect distribution uniformity?
It matters only through the measurements supplied to the formula. Confirm lowest-quarter average for the relevant area or period.
