Pump Head-Pressure-Specific Gravity
Head and Pressure Conversion
Liquid Head in feet = psi x 2.31 Sp. Gr
Pressure in psi = Head in feet x sp gr 2.31
Liquid Head in feet = psi x 144 W
Pressure in psi = Head in feet x W W
Where W = Specific weight in pounds per cubic foot of liquid being pumped under pumping conditions: For Water W = 62.32 lb per cu ft at 68 degrees F.
