Answer / nitin sompura

See as per your data open tank height is 2.5 mtr
(2500mm).zero and 100% level if we consider as per your
tank and we suppose no safety margin for overflow as well
as for zero level for the pump, as you have not mentioned
clearly,
so according to you please keep your LP of DPT in
atmosphere, and HP point connect to the bottom of tank,and
if we consider tank of water then LRV:0.0mmWC,URL:2500 mmwc.
as per your medium you consider density.
