Hi bobby,
I am using efficiency value from this attached graph. This is from Book COMPRESSORS Selection and Sizing by ROYCE N BROWN. But still I am away from correct result.
Second thing is about frame friction. How to consider frame friction in calculated power. And in previouse performance sheet Stage power is (w/Friction). What is meaning of w/Friction.
Another confusion with effect on power due to valve loss. how to consider valve loss in power calculation
Thanks
Brijesh
You need to check both mechanical efficiency and adiabatic efficiency. There are no mysteries to calculating theoretical adiabatic compression power requirements.
