The volume of a 3-inch pipe that is 1,000 feet long is: 49.09 cubic feet.
The volume would be 180,400 m3
300×3=600 so 1000ft > 300yd
First step is to calculate volume in the pipe. The volume contained in a 5in diameter section of pipe that is 12in long can be calculated by multiplying the area of a 5in diameter circle by the length of the pipe, in this case 12in. To determine the area of a circle you use the following formula: Area = Pi x radius^2 Area of 5in circle = 3.14 x (2.5in)^2 Area of 5in circle = 19.6in^2 We then multiply this "cross sectional" area of the pipe by the length. 19.6in^2 x 12in = 235.2in^3 Wikipedia tells me that the volume of a US Gallon is 231in^3 To determine the number of gallons in the section of pipe we divide our calculated volume by the defined volume for a US Gallon. Notice the units are the same! Volume in pipe/ Volume of US gallon = 235.2in^3/ 231in^3 = 1.018 Gallons
pi*radius2*length
The volume of one foot of 3-inch PVC pipe is: 84.82 cubic inches. In terms of liquid, this equates to about 0.3672 (US) gallons or 47 fluid ounces for that section of pipe.
333 1/3 yards
3 inch (inside diameter) pipe = 0.25 feet. Radius = 0.125 ft Cross section area = pi*(0.125 ft)2 = pi * 0.015625 ft2 . Multiply by 80 ft = pi * 1.25 cubic feet = 3.926990817 cubic feet x 7.480517578 (US gallons / cubic ft) = 29.37592384 US gallons.
Volume = pi1210 = 31.416 cubic feet rounded to 3 decimal places
What pressure or are you asking drainage THEN What pitch are you using
That all depends on how long said 3" pipe is?
Depends on how long the pipe is
Use the formula for volume on a cilinder that is 1' high and 3/4" in diameter and multiply by 4000 feet.
