Packed cell volume formula
WebA hexagonal closed packing (hcp) unit cell has an ABAB type of packing. For calculating the packing fraction we require the volume of the unit cell. Volume of hcp lattice = (Base area) ⋅ (Height of unit cell) Each hexagon has a side = 2 ⋅ r. Base area = 6 (Area of small equilateral triangles making up the hexagon) WebThe mean corpuscular volume, or mean cell volume ( MCV ), is a measure of the average volume of a red blood corpuscle (or red blood cell ). The measure is obtained by multiplying a volume of blood by the proportion of blood that is cellular (the hematocrit ), and dividing that product by the number of erythrocytes (red blood cells) in that volume.
