Centrifugal Fan Module — MOE Lab Tender Details

Centrifugal Fan Module

Allows students to study and perform tests on a centrifugal fan:
to understand how it works and calculate its performance.
The equipment should connect to a Versatile Data Acquisition System.

Experiments
Performance of a centrifugal fan
Variation of fan performance with speed
Variation of fan performance with type of impeller
Non-dimensional performance curves
Determination of the specific speed of the fan
