Air at 293 K and 100 kPa is accelerated by being sent to the nozzle after being compressed to 500 kPa in a compressor with a mechanical efficiency of 85%. The pressure at the nozzle outlet is measured as 100 kPa. Considering that the air behaves as an ideal gas, its heat capacity is constant, the nozzle operates adiabatically and reversibly, and the velocity at its inlet is negligible: a) The temperature at the compressor outlet (K) and b) Calculate the velocity (m / s) at the nozzle outlet.
