Question

A turbine receives air at 1500 K, 1000 kPa and expands it to 100 kPa. The turbine has an isentropic efficiency of 85%. Find the actual turbine exit air temperature and the specific entropy increase in the actual turbine.  

Answer 1

C.V. Turbine. steady single inlet and exit flow. To analyze the actual turbine we must first do the ideal one (the reference).
