The kinetic energy of a fluid increases as it is accelerated in an adiabatic nozzle. Where does this energy come from? Explain (in brief) using the appropriate equation. An ideal gas enters an adiabatic, horizontal, nozzle (fixed on the ground) at 300 kPa, 200°C and 30 m/s, and leaves at 100 kPa and 180 m/s. These conditions are maintained for all time.
