The compressed air flow in the pneumatic networks is studied from thermodynamic point of view. Generally speaking, the flow issue is presented as next: knowing the characteristics p1 (pressure), v1 (specific volume), T1 (temperature) and the fluid speed w1, in the initial section (point 1), of a specific pipe section. It is asked the determination of the p, v, T and w characteristics in a certain section. Presuming the compressed air is a monophasic homogeneousness fluid, the conservation laws using allows the determination of the equations that rules the fluid evolution. On the basis of the Fanno flow analysis could be proposed a model for the characteristics p, v, T, w values calculation. The proposed model validation is made means the experimental data, obtained through “in situ” exploration of a pneumatic mining network.
