I have an industrial application where 20kW of heat is being wasted, which is painful to watch. I have learned already that low temperature turbines just don't work, so would like to check some ideas and better understand how air motors/turbines work. I have also learned so far that η=1-(Tout/Tin), however I don't think this takes pressure into account. This is where I am lost.
Let's say I have a closed system with air or other refrigerant:
* input at 1000 kPa, 50ºC, 1kg/sec
* scroll motor with expansion rate of 1:10
* output pressure at 100kPa
How do I go about calculating:
* input power?
* output temperature?
* mechanical power produced?
Is there anything missing?
