Classification: CPC G | IPC G

Claim 14:
15. The method of claim 12, further comprising:
selecting a relationship between values of electric power consumption of the at least one cooling fan and values of volumetric airflow rate provided by the at least one cooling fan that corresponds to the determined current rotational speed of the at least one cooling fan, the selected relationship being selected from multiple relationships between values of electric power consumption of the at least one cooling fan and values of volumetric airflow rate provided by the at least one cooling fan, each of the multiple relationships being defined for a different rotational speed of the at least one cooling fan; and
determining a current real time volumetric airflow rate of the cooling air circulated from the cooling air inlets to the cooling air outlets through the enclosed interior of the chassis enclosure by the at least one cooling fan to be a volumetric airflow rate value from the retrieved relationship that corresponds to the determined current real time value of electric power consumption of the at least one cooling fan.
