Additional pins for the ventilation system as a whole
1. The total pressure in the cross section of the air intake duct is
present, although it has a small value.
2. Static pressure in the cross section of the exhaust outlet of the
discharge duct is present, although it has a small value.
Conclusion
1. Only by applying the new theory in the fan selection method (in this
case, the centrifugal one) can one obtain the exact “working point of
the fan” and other reliable parameters.
2. New theory can later be transferred to other types of a fans.
