a turbine that As depicted in the schematic below, air flows steadily through produces rotational, mechanical work at a rate of 520 kW. Inlet and exit conditions are shown in the schematic, where pressures indicated at the inlet (1) and exit (2) are absolute pressures. The specific heat of air at constant pressure, Cp, is 1.01 kJ/kg-K, and the specific gas constant for air, R, is 287 J/kg-K. D = 15 cm P = 1030 kPa T = 150 C V = 30 m/s Turbine a) Calculate the exit velocity, V. [4 marks] ANS: 72.7 m/s WM,R = 520 kW Q = ?
