I Think what your talking about is a Cylinder?
A sample tube, culture tube, sometimes a boiling tube.
The tube is used to store the gasses from the cylinder.
To calculate the mass of a hollow tube, you need to know the outer diameter, inner diameter, and length of the tube. First, calculate the volume of the tube by subtracting the volume of the inner hole from the volume of the outer cylinder. Then, multiply the volume by the density of the material to determine the mass.
