Packing factor is a dimensionless ratio that describes the amount of volume that a substance takes up in a particular volume. For example, if you have a box and you fill it with balls, the volume of the box is taken up by the balls and by the space in between the balls. The packing factor would be (volume of the balls)/(volume of the box). Packing factor is, among other things, relevant to the arrangement of atoms in different crystallographic structures.

If you are referring to the stem packing, you should be able to do it with no problem under pressure. Shut the valve off, take off the handle, then the nut with the packing in it, remove the old packing, replace it and reinstall the nut and handle. Open the faucet completely and that should be it.. Some valves use a rubber formed packing instead of the graphite or Teflon rope packing. Generally you can use either in place of the rubber or use a small amount around the stem with the old rubber.
A packing puller, hook or pick is a device that looks like a corkscrew on the end of a rigid or flexible shaft. They are made of different sizes to fit between the shaft and casing of a stuffing box of various size pumps and valves. The screw is twisted into the soft packing and then it is pulled out of the stuffing box. A packing pick is one of three tools that look like dental picks for removing leftover scraps of packing or for getting into tiny valve stuffing boxes.

Na Cl has an IPF factor not APF as it is compound and APF refer to atomic packing factor, not ionic packing factor.
Are you referring to the packing factor in Crystallography? This is the proportion of volume taken up by atoms compared to the total volume. See Wikipedia entry for Atomic Packing Factor
Yes, packing factor does affect density. Packing factor refers to how closely atoms are packed in a material, which in turn influences the material's density. Materials with higher packing factors will have higher densities because the atoms are more closely packed together.
.74
Packing factor: In a simple way it is the ratio between the mass of tightly packed (compacted) to the mass of lossely packed.
The atomic packing factor for rock salt is 0.74. This means that 74 of the space within the crystal structure is occupied by atoms. The high packing factor results in a closely packed arrangement of ions in a cubic structure, giving rock salt its characteristic high density and stability.
Pre- packing is packing before a trip or where ever you are going. =P
The plural of "packing list" is "packing lists." In English, when forming the plural of a compound noun like "packing list," the plural is typically formed by adding an "s" to the main noun in the compound, in this case, "list." Therefore, to indicate more than one packing list, you would use the term "packing lists."
The packing fraction of hexagonal close packing is about 0.74, which means that approximately 74 of the available space is occupied by atoms in this arrangement.
In body-centred cubic structure,The no. of atoms per unit cell= 2Volume of 2 atoms (spherical)=2*(4/3)πr3We know the radius of atom in BCC isr = a√34Volume occupied by the atoms per unit cell(v) = 8πa√33 4v == 8πa33√3------- ---------3 4*4*4Volume occupied by the atoms per unit cell(v) =πa3√3----8Volume of the unit cell for a cubic system(V) = a3Atomic packing factor (APF) =(πa3√3/8)--------------a3√3(or) APF =π---------8APF = 0.68Therefore, we can say that 68% volume of the unit cell of BCC is occupied by atoms and remaining 32%volume is vacant.Thus the packing density is 68%.
