A compacted body of iron powder is sintered into a 20mm-diameter, 45-mm-tall cylinder which, upon weighing, is found to have a mass of 98g. Calculate the apparent density, the percentage of theoretical density, and the void volume (porosity) in percent.
Density is mass/volume.
The volume of the cyclinder is pi*r^2*h (4.5E-6*pi m^3).
This solution provides a simple explanation for finding density and volume using density and mass amounts.
