Dear Sasi,
This is a specialized work;you require to refer/consult standard code(s) e.g API, NFPA etc.
However you must envisage the On-Fire Tank/equimpent scenario and all the nearby structures tankage(s) effected by the radiant heat from fire and Fire water needs for all such risks on downwind/upwind side etc.
Hope this gives general clarification for you to check/study for further work.
Best regards

Read NFPA 15. It has guidelines on water demand per area of equipment. Good luck!
