I assume your dimensions are outside diameter 20mm, 3mm wall, 3m long.
If so, then the volume is π*((.01)^2-(.01-.003)^2)*3=.0002853 cubic meters. or 285.3 cubic centimeters.
In order to know the mass, however, you have to also know the density.
Is it a copper pipe? If so, its mass is 8.92*285.3= 2.545 kilograms
Is it PVC? If so, its mass is 1.38*285.3 = .394 kilograms
In general, mass is volume times density.
The volume of water in one meter of a 22mm-diameter pipe is: about 0.1 US gallons.
It takes 24.50985 feet of 1 inch pipe to hold one gallon of water. Jeff Payne jpayne@texwipe.com
Normally erw pipes having the sizes of 1/2, 3/4, 1, 2 inch etc also Poly ethylene pipe having the size of dia of 20mm,32mm,60mm,90mm,125mm etc
No, it is not true; the law remain valid.
The volume of a cylinder (pipe) is: pi*(r^2)h If a pipe has an 8 inch radius, then to find the volume you substitute: V = pi*(8^2)h If a pipe has a 4 inch radius, then to find the volume you substitue: V = pi*(4^2)h Thus, an eight inch pipe can carry 150.72*h more units cubed.
20mm
It means 20mm Nominal Bore or 20mm inside diameter piping.
Well, first you need to gather more information. Density= Mass/Volume, so you will need to find the mass in grams of this metal pipe and then calculate the volume. I am assuming that the pipe is going to be a nice even cylinder, so use the circular cylinder volume formula. Then, divide mass/volume, and your answer will be in g/cm3.
Google volume of a cylinder. once you have the volume, plug in the density of water to get the mass.
The volume of this pipe is 28,510,000 mm3
You calculate its volume, look up the density of bronze, then multiply volume x density to get mass. Probably that's what you want; if you really want weight, you multiply mass x gravity to get the weight.
Calculate the volume of the outer cylinder as pi*r*r*h where pi = 3.14159, r = 195, and h = 3400. Calculate the volume of the inner cylinder with r = (195 -25) = 170. The difference between the two is the volume of MS (steel used). density = mass / volume mass = density * volume. weight = mass * gravity (= 9.8)
You calculate its volume, look up the density of bronze, then multiply volume x density to get mass. Probably that's what you want; if you really want weight, you multiply mass x gravity to get the weight.
The volume of this pipe would be 0.3817 m3
The volume of the pipe is 1,154.5 cubic feet.
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.
