In the calibration jar method, s represents the number of seconds required to fill which container?

• A. A 1-Quart Jar
• B. A 1-Gallon Can
• C. A 1-Liter Bottle
• D. A 1-Pint Jar

Answer: (A)

The calibration jar method uses the time it takes to fill a container of known volume to determine flow rate. The s value is simply the number of seconds required to fill that container. A 1-quart jar is used because it’s a convenient, manageable volume (0.25 gallons) that fills quickly and gives a clean, easy-to-calculate result. Once you have s, convert to minutes and calculate flow rate: gpm = volume in gallons divided by time in minutes. For a 1-quart jar, gpm = 0.25 / (s/60) = 15/s. So if it takes 30 seconds to fill, the flow rate is 0.5 gpm. This small, precise container keeps measurements straightforward and accurate.
