Water Data and Formulas
1 gallon water = 231 cubic inches = 8.333 pounds
1 pound of water = 27.7 cubic inches
1 cubic foot water = 7.5 gallons = 62.5 pounds (salt water
weighs approximately 64.3 pounds per cubic foot)
Pounds per square inch at bottom of a column of water =
height of column in feet x .434
Horsepower to Raise Water
If pumping liquid other than water, multiply the gallons per
minute below by the liquids specific gravity
Gallons Per Minute through a Pipe
GPM = .0408 x pipe diameter inches
2
x feet/minute water
velocity
Weight of Water in a Pipe
Pounds water = pipe length feet x pipe diameter inches
2
x .34
Horsepower = gallons per minute x total head in feet

Measures of Pressure
1 Pound Per Square Inch = 144 Pounds Per Square Foot = 0.068 Atmosphere = 2.042 Inches of Mercury at 62°F = 27.7 Inches
of Water at 62°F = 2.31 Feet of Water at 62°F.
1 Atmosphere = 30 Inches of Mercury at 62°F = 14.7 Pounds Per Square Inch = 2116.3 Pounds Per Square Foot = 33.95 Feet of
Water at 62°F.
1 Foot of Water at 62°F = 62.355 Pounds Per Square Foot = 0.433 Pounds Per Square Inch.
1 Inch of Mercury at 62°F = 1.132 Feet of Water = 13.58 Inches of Water = 0.491 Pounds Per Square Inch.
