Figures are to be used as a guide since the hose inside diameter tolerance, the type of fittings used, and orifice
restriction all influence the actual discharge. Thus, variations plus or minus from the table may be obtained in actual service.

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
1 miner's inch = 9 to 12 gallons per minute
Horsepower to Raise Water
If pumping liquid other than water, multiply the gallons per
minute below by the liquids specific gravity
