Q2: In a single-stage gas turbine, gas enters and leaves in axial direction. The angle is 68°, the stagnation temperature and stagnation pressure at stage inlet are 800°C and 4 bar, respectively. The exhaust static pressure is 1 bar, total-to-static efficiency is 0.85, and means blade speed is 480 m/s, Assume y = 1.33, and Cpg = 1.147 kJ/kgK. Determine 1. The work done, 2. The axial velocity which is constant through the stage, 3. The total-to-total efficiency, and 4. The degree of reaction.
