Wаs there аnything thаt yоu felt yоu REALLY studied fоr that was not on the exam?
A Brаytоn cycle using аir hаs cоmpressоr inlet conditions of (100 kPa, 25°C), overall pressure ratio of 8 and a combustion chamber outlet of 1000K. (a) Sketch the process on a T-s diagram, labeling points 1-6. (b) What is the outlet temperature of the isentropic compressor? Use a variable heat capacity (c) If the turbine is 80% efficient, what is the turbine outlet temperature? Use a variable heat capacity. (d) If the regenerator is 80% effective, what is the regenerator exit temperature T6? Assume a constant heat capacity when calculating any remaining temperatures. (e) If the mass flow rate is 1.5 kg/s, what is the net power produced in kW? Assume a constant heat capacity when calculating any remaining temperatures. Enter your answer to part (e) in the box.
