It depends on what you mean by a 30 pipe.
Is 30 the cross sectional area - in which case, what is the length of the pipe?
Is 30 the length - in which case, what is the cross-sectional area?
The volume of the pipe is 1,154.5 cubic feet.
There is no obvious reason why there should be any water in the pipe. Furthermore, there are no units associated with the width of the pipe, so its volume cannot be calculated.
measure the radius of the pipe. (half the diameter - the width of the pipe) then measure the length of the pipe. then use the formula pi (3.14) x radius2 x length. the answer is the volume in the pipe
The volume of a 12 inch x 12 inch pipe is: 1,360 cubic inches
Consider the volume of the pipe as the difference in the volume of two cylinders, one containing the whole pipe and the other the empty space inside. Use the formula for the volume of a cylinder : Pi*r*r*h. Find the volume of the first cylinder with the larger radius and subtract from it that of the cylinder with the smaller radius. The height (or length) is the same for both volume calculations. The result of subtracting these is the volume occupied by the pipe.
The volume of the pipe is 1,154.5 cubic feet.
245 cubic feet.
This pipe has a volume of 24.5 cubic feet.
The volume of this pipe is 28,510,000 mm3
Area = pi x radius^2 Multiply that answer by 30feet and you have the volume of the pipe.
There is no obvious reason why there should be any water in the pipe. Furthermore, there are no units associated with the width of the pipe, so its volume cannot be calculated.
This is dependent on the internal diameter of the pipe. Your answer is the volume of a circle multiplied by its length (the volume of a cylinder) volume = (PI*RadiusSquared)*height so a pipe 1 metre long with an internal radius of 4cm volume = (3.142*16)*100 =5027.2 millilitres 5027.2/1000= 5.0272 litres
This pipe will hold 706.9 cubic meters of water or 186,700 US gallons.
A pipe that is 30 inches in diameter and 12 feet long has a volume of: 440.6 US gallons of water.
The volume of this pipe would be 0.3817 m3
The internal diameter of the pipe times pi times its length will yield the volume it can contain. The outer diameter of the pipe times pi times its length will yield the volume that the pipe will displace when it is submerged or buried. The volume the pipe will displace minus the volume it will contain will yield the volume of material that makes up the pipe.
The volume of this pipe is 261.8 cubic feet.
