2. A turbine receives air at 50 kPa, gauge and 800 K. It discharges to 0 kPa, gage, and the outlet temperature is measured as 500 K. The mass flow

rate is the same as in the previous problem. Determine: A. the maximum work the turbine.can do under these conditions. B. the heat loss, if the turbine works isentropically.
