The safe height (h) to diameter D. ratio (i.e., h/d) for liquid/petro fuel storage tank of capacity more than 45 kilolitres is less than _________________?
Correct answer: A. 1
- A. 1
- B. 2
- C. 3
- D. 3.5
Explanation
For liquid or petroleum-fuel storage tanks above 45 kL capacity, the recommended safe proportion is a height-to-diameter ratio below 1. A relatively broad tank improves stability and reduces excessive liquid head and wind effects.
