Hello everyone,
I am trying to evaluate the actual performance of the centrifugal compressor.
Vendor has provided performance curves at single speed (let us say- X RPM) only.
In actual, compressor is running at different speed (let us say - X / Y / Z etc).
How can we obtain new curves at running or operating speed.
I tried using affinity or fan laws, but that is not giving satisfactory results at much higher speed than the speed (X RPM) given by vendor. At near about similar RPM (X RPM), results are matching with performance curves.
How to tackle such situation.
