Задача id13964

Air, compressed in a large cylinder at a temperature T1 = 273 K, flows into the atmosphere through a tube, at the end of which it acquires a speed v = 400 m/s. Find the temperature of the flowing air T2 at the end of the tube, as well as the pressure P1 of the air in the cylinder. The gas outflow process is considered adiabatic.
