Notes :
1) M = 160mm
2) Section length = Section length modulus x 160 + 50 (mm)
3) The total length of the unit = ? (All the section length modulus) x 160 + The quantities of sections x 50 (mm)
4) The principle to define the length modulus of the section is choosing the smallest modulus because there are multiple choices for the same airflow
