Groundwater Sampling Information

EnviroTech Services Company is eclipsing its 30 year in business as a certified small business enterprise.

Volume Formula

Volume = p x r2 x h
Curved surface area = 2 x p x r x h
End surface area = 2 x p x r2

Water Data & Formulas

1 gallon water = 231 cubic inches = 8.333 pounds (@ 65°F)
1 pound of water = 27.72 cubic inches (@ 65°F)
1 cubic foot of water = 7.5 gallons = 62.4 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 0.434 (39°F)
1 miner’s inch = 9 to 12 gallons per minute


Horsepower to Raise Water

Horsepower =
gallons per minute x Total Head in feet
3960


(if pumping a liquid other than water, multiply the gallons per minute above by the liquid's specific gravity)
