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.
high density polyethlene pipe
Low Density a Metal?NO!!!!
Every metal has a density.
The density of the metal in the crushed can remains the same as the density of the metal before it was crushed. Density is an intrinsic property of a material that does not change with physical alterations like crushing. So, the density of the metal in the can will not change due to the crushing process.
This is hard to answer with out knowing what type of metal. what the pipe is being used for, the amount of pressure that may be not the pipe.
The base metal is iron - the active metal is zinc (galvanized)
If you cut a metal in half, each half will have the same density as the original metal, so the density of each half will still be 8.4. The density of a material does not change when you cut it into pieces.
The density of the metal will remain the same. However because the volume of the object has been reduced the overall density will increase
The density of the metal in a crushed can remains the same as the density of the metal before the can was crushed. The mass of the metal remains constant; only its shape changes when the can is crushed.
how would density of a metal be affected if it were wet
The density of the metal in a crushed can remains the same as the density of the metal before the can was crushed. While the volume of the can decreases when it is crushed, the mass of the metal remains constant. Therefore, the density, which is mass divided by volume, remains unchanged.
If it is a copper or metal pipe, tap the pipe gentle with a some thing metal (screw driver/small wrench ect...) If the pipe makes a echo sound it is empty, if the pipe has water in it, It will not echo. this also works with pro pain bottles and other metal objects
