Computational methods of filling silica gel in industrial chromatographic columns

I Volume of column:

Diameter is d, radius is r, height is h.

Volume

V=πr²h=π×（d²÷4）×h

For example: height of volume is 3 meter, diameter is 309mm (772.5px), volume is following: Volume of column=π×（30.9²÷4）×300=3.14×（30.9²÷4）=224858ml≈225L. Therefore, volume of column is 225L.

II Calculating silica gel in column.

Columns in 3 meter can load 300-400 mesh silica gel in 100-200kgs.

Load 100kg in average, volume per liter can fill 0.44Kg silica gel. 100÷225=0.44Kg/L

Volume of 1kg silica gel is 2.25L (225÷100=2.25L/Kg)

III If the client decides to fill 150Kg silica gel, what is volume? V=2.25×150=337.5≈340L

IV What is height of the column in R400mm,150kgs? h=（340×10³）÷（3.14×20²）=270.7CM≈2.7meter.
