Measure a dripping faucet with a container
A resident collects 0.15 L in 15 minutes, giving 0.01 L/min. A repeat test after the handle is closed again collects 0.075 L in 15 minutes.

What the comparison shows
If each measured rate continued for a month, the lower rate would produce half the volume. The two readings show how a projection depends on the sampled flow.
Assumptions and limits
Container measurements are stronger than assuming a universal drop size. A short sample may miss changes during the day.
