Multi Stage Centrifugal Demonstration Unit

The unit consists of a small multi stage air compressor with a motor on a steel base, inlet and outlet ducts, sensors and software. Speed control is by a variac. Multi Stage Centrifugal Demonstration Unit is a bench top unit for studying the multi stage centrifugal air compressor characteristics with data analysis by computer.

Experiments:
Effect of speed on compressor performance.
Flow rate vs pressure.
Compressor input, output, and overall efficiency.
