Centrifugal Compressor Module — MOE Lab Tender Details

Centrifugal Compressor Module

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

Experiments
Performance of a compressor
Variation of compressor performance with speed
Investigation of non-dimensional characteristics
Comparison of performance with that of an ideal adiabatic system
