9. Steam enters a converging-diverging nozzle at steady state with P₁ = 40bar T₁ = 400°C and a velocity of 12m/s. The steam flows through the nozzle with negligible heat transfer and no significant change in potential energy. At

the exit P₂ = 15bar and the velocity is 700 m/s. The mass flow rate is 2.5 kg/s. Determine the exit area of the nozzle in m². [MO1, MO2, MO5]
