How many gallons of water are in a 4 inch pipe 120 feet long?

Answer 1

A 14 inch diameter pipe has cross sectional area 154 sq ins, so 1 foot length = 12 inches will have volume 1848 cubic inches.

1 US gallon = 3.8 liters = 3800 cubic centimeters(cc). 1 cubic inch = 16.39 cc. So 1 US gallon = 231.85 cubic inches. So 1 foot of pipe will contain 1848/231.85 = 7.97 gallons, say 8 gallons.

Answer 2

To find the number of gallons in a foot of pipe of any diameter: Multiply the square of the diameter of the pipe in inches by .0408.

In this case 4^2 = 16 16*.0408=.6528 gallons per foot of pipe

Answer 3

Since 15 inches is not a nominal pipe size it must be assumed that you are measuring the internal diameter of the pipe and the size of the outer wall can be ignored.

What you are seeking can be described as the volume of a cylinder. The volume of a cylinder is the value of pi times the radius of the pipe (one-half the diameter or 7.5 inches) squared times the length of the cylinder (12 inches). That calculation will give us a number of cubic inches.

A gallon of water takes up 231 cubic inches.

Pi times 7.5 squared is 176.72 square inches (this is the area of a circle, a pipe is just a whole lot of circles - 12 inches worth in this case)

176.72 square inches times 12 inches (the length) is 2,120.6475 Cubic inches.

2,120.6475 cubic inches divided by 231 cubic inches (the volume of a gallon of water) is 9.1803 gallons.

Answer 4

assumption: 1.4 inch is the inside diameter of your pipe.

answer: Your total volume of water would be:

diameter: 1.4 inch/12 = 0.1166 feet

volume of water would be pi * (0.1166/2)^2 * 60 = 0.64 cubic feet

pi=3.141592..... (you just got to know pi to a certain number of digits)

now there are 7.48 gallons of water per cubic foot.

Therefore 0.64 cubic feet * 7.48 gallons /cubic foot = 4.79 gallons of water (in your pipe)

Answer 5

Assuming the 30 inches is the inside diameter, the volume is 2.5 cubic ft. 1 cubic foot will hold 7.481 gallons of water. 2.5 cu ft = 18.7025 gallons

Answer 6

A 14-inch inside diameter pipe 120 feet long has a volume of 18,472.56 cubic feet or 138,184.34 gallons.

Answer 7

About 78.3 gallons.

Answer 8
