What is the power output (kW) of the first stage of an axial flow turbine which takes 600 kg/s of gas at 1550C and 20 bar stagnation conditions? After passing through the nozzle, the flow leaves nozzle at a direction 70 degrees from that of axial, at a velocity of 680 m/s, as given in figure, and discharges it from the bucket (rotor) without swirl (c8,2 = 0). The pitch diameter of the bucket is 1 m, and the shaft speed is 3600 rpm. The turbine has an isentropic stagnation-to-stagnation stage efficiency of 90 percent.
