Wet Well Or Reservoir Elevation For Suction Lift

Velocity head Friction head Static head Suction head = Suction-side static head Suction-side friction head

SUCTION HEAD (hs)—Reduces the pressure differential that the pump must develop when a positive head is on the suction side (a submerged impeller). If the water level is below the pump, the suction lift plus friction in the suction pipe must be added to the total pressure differential required.

TOTAL HEAD (H)—Expressed by the following equation:
