Steam enters a converging-diverging nozzle at 1MPa and 400°C with a negligible velocity at a mass flow rate of 2.5 kg/s, and it exits at a pressure of 200kPa. Assuming the flow through the nozzle to be isentropic, determine the exit area and the exit Mach number.

Given-
R₁ = 1 MPa
T₁ = 400°C = 673K
Velocity, C₁=0.
To Find:-

(₁) A₂ = ?
(ii) Mach no., M=?
Soluti .. Velocity at exit,
As we know,
π
=) (2 = √2Cp (T₁-7₂)
⇒ ₂2 = √√2x1005 (673-424-92)
=) C₂ = 706.143 mls.
