Air flows through a well-insulated nozzle operating at steady state. At the inlet, the pressure is 4 bar, the temperature is 525 K, and the velocity is 122 m/s. At the exit, the pressure is 2.5 bar and the temperature is 470 K. Neglecting potential energy effects, determine the velocity at the nozzle exit in m/s. Assume the ideal gas model is applicable.
