A gas turbine stage develops 3.4MW for a mass flow of 27 kg/sec. The stagnation pressure and temperature at the stage entry are 772 kPa and 1000K. The axial velocity is constant throughout the stage, the gases entering and leaving the stage without any absolute whirl. At the nozzle exit, the static pressure is 480kPa and the flow direction is at 72°. Let C,=1.148, R=0.287. Determine the following: a) the axial velocity, b) the degree of reaction for the stage given that the entropy increase in the nozzles is 13 1/(kg °C)
