A C-D duct is connected to a large air reservoir with Po = 300 kPa, To = 400°K. The exhaust from the end of the divergent section of the duct is supersonic. a) Assuming ideal expansion, find Agxit (m²) when the throat area is A" = 2 m? and the back pressure is p, =60 kPa. b) Find the new Aexit required to maintain ideal expansion if the back pressure is raised to p, = 80 kPa.
