8.18 Sizing the Auxiliary Fan

drive to comply with regulations concerning maximum permitted air velocities in
underground works.
(x) Before providing any result, students should check, at least, if their answers lie
within the normal range. If we have a look at the last paragraph of Sect. 8.18, we
can see that auxiliary fans usually provide up to 28 m s
−1 at up to 3.7 kPa. Therefore, airflow requirements in the exercise are high. As the main reasons for this,
we can highlight the high level of leakage and the fact that estimates for the
machinery working in the tunnel at the same time could well be too large (the
use of simultaneity factors would have been more appropriate). Moreover, the
velocity at which air circulates inside the duct is above that generally recommended for this kind of duct (20 m s
−1 ). For this reason, it would be advisable
to modify the design, taking into account these considerations.
