7.3 Flow rate calculation

The flow rate is calculated using the effective pressure method. This involves comparing the static pressure upstream of 
the inlet nozzle with the static pressure in the inlet nozzle.
The flow rate can be calculated from effective pressure Δpw (differential pressure of the two static pressures) using the 
following equation.
The doors must be closed to determine the correct flow rate. Route the test hoses to the outside when conducting the test.
Due to the installation conditions of the fans, K values differing from the manufacturer's specifications must be used for 
flow rate determination.

7.3.1 Effective pressure calculation

Δp = Effective pressure (symbolic representation).
