Pure iron powder is to be compacted and sintered into a complex shape, the bulk volume of which is not easily measured. The following weights have been experimentally determined for the sintered product:

Weight in air = 95.00 g Weight suspended in water = 82.65 g Weight saturated with water = 96.80 g

Calculate: (a) open pore volume, (b) true volume, (c) apparent volume and closed pore volume, and (d) percentage of theoretical density. The true density of iron is 7.87g/cc.
