Formula A
In this formula, the respective air density at
the fan is taken into account.
The air density must be determined as a
function of air temperature, air humidity, sea
level and atmospheric pressure.
With the following formulas, the airflow rate can be determined from the pressure signal:

V07-19.0
Formula B
In this formula, a variable air density is not taken into
account.
Instead, a "fixed" air density of 1.20 kg/m
sumed.
