Calculating Brake Horse Power for Centrifugal Fan Drive System

[kshenq85]

Dear all,

I need some help regarding about calculating the Brake Horse Power (BHP) from a Centrifugal Fan Drive System.

Basically, this Centrifugal Fan is a pulley driven using a 3 phase Induction Motor.
Based on the pulley selection program, they provide some values such as:-

1) Static Eff.
2) Fan Power
3) Motor Power
4) Fan Speed
5) Specific Fan Power.

I am not sure if these values are useful.

Therefore, how can I derive the BHP value for this Centrifugal fan drive system.

What information do I need in order to get this value? Please help to enlightened. Thanks.

Air volume/time * pressure increase = power.
