  • Modern compressible flow by John D Anderson

    Eq. (5.28)

    Eq. (5.24)

    = (0.6/1) × (0.5/0.25) = 1.2

    Me2 = -1/(1.4 - 1) + √(1/(1.4-1)^2 +2/(1.4-1)×〖(2/(1.4+1))〗^((1.4+1)/(1.4-1))×〖(1/1.2)〗^2 ) = 0.223

    From Table Isentropic flow properties

    Mepoe/pe

    0.2201.0343

    Eq. (5.29)

    po2/po1 = 1.0343 × (0.6/1) = 0.621

    From Table Normal shock properties

    Mpo2/po1

    1.22000.6281

    From Table Isentropic flow properties

    MA/A*

    1.22001.0366

    The local area ratio at which the shock is located inside the nozzle is 1.0366
