Air flows steadily from a high pressure container (A) to a
low pressure container (B) through an ideal convergent-divergent nozzle. Find
the flow area at the throat and at the exit of the nozzle. Data: mass flow
rate: 2 kg, air pressure in container A: 700 kPa, inlet temperature: 116 C, air
pressure in container B: 70 kPa.
