Explanation:

For question 4: Fire demand can represent a very high portion of water storage needs, as in some cases the full storage capacity may be allocated to meet fire suppression requirements.
For question 5: To prevent short-circuiting (where incoming water mixes directly with outgoing water without proper storage turnover) and ensure proper water quality and system functionality, separate inlet and outlet piping is a standard recommendation for storage tanks.
