<p>Air enters an adiabatic nozzle steadily at 300 kPa, 200&#176;C, and 30 m/s and<br />leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm2. Determine<br />(a) the mass flow rate through the nozzle,<br />(b) the exit temperature of the air, and<br />(c) the exit area of the nozzle.</p>
