Hi all, does anyone knows of any good website that teaches you how to read turbine or compressor maps? And possibly teaches you how to select the best turbine / compressor for your particular application?

Turbines and compressors are quite different animals. Compressor curves are normally the predicted discharge pressure, efficiency, temperature, versus flow for one or more operating speeds. The curves are plotted from the surge point to the choke point.
For the compressor application, you need to let the manufacturer know the conditions you want to meet. This will consist of inlet and discharge pressures, inlet temp, gas composition, mass flow rate, driver speed if you have one. For the turbine, the steam inlet pressure and temp, exhaust temp., operating speed, power required, and available flow.
There's a good bit more that goes into the selection of turbines and compressors but this is a start.
Any good turbo machinery text will provide detailed information about all the things are you looking for.
