Water storage tanks have a nominal capacity of 4360 gallons with what tolerance?

• A. 4360 gallons
• B. 4360 - 25 gallons
• C. 4360 + or - 25 gallons
• D. 4360 + or - 50 gallons

Answer: (C)

Nominal capacity is the designed volume, but real tanks can vary a little due to manufacturing and measurement tolerances. For this tank, the tolerance is plus or minus 25 gallons, so the acceptable range is 4335 to 4385 gallons. This keeps the tank within spec without requiring exactly 4360 gallons every time. A zero tolerance (exactly 4360) isn’t practical, and a wider tolerance like plus/minus 50 would be less precise than standard practice.
