I am struggling with how a compressor's efficiency is calculated.

This is the set up:

I have a Garrett T3 compressor housing being spun by an electric motor.

I can measure the airflow in, the airflow out, the pressure and temperature on both sides of the compressor, the power being used by the motor and the rpm the thing is spinning at.

Can someone give me a nice simple equation to calculate the efficiency and explain please?

Please consider I am not a physics or engineering major and do not not have a degree in mathematics.

Laymen's terms would be appreciated.

Thanks guys
