to stookeyfpe:
the system demand is 198 gpm w/o considering the hose allotment and demand pressure of 42 psi. if the overhead tank alone, only 20 psi approximately is available against a demand of 42 psi, from my point of view the overhead tanks are not sufficient enough to meet the system...
GOOD DAY!!
I just want to raise a question here bout overhead tank combined with a basement cistern.
I was assigned to design a 15,000 gal capacity sprinkler system, the problem was the source of supply consists of this: two(2) 5,000 gal overhead tank and one(1) 5,000 gal capacity basement...
I just need to clear my mind on this...how should I specifically design the cut-in cut-out for both fire pump & jockey pump? Appreciate feedback on this. Thnks.
