Question
Example 2 An air stream with
a Mach number of (3.04) a
pressure of (302 kPa) and a
temperature of (502 K) enters a
diverging channel. If the ratio of
the exit cross- sectional area to
the inlet cross- sectional area is
(3). Determine the back pressure
which is necessary to produce a
normal shock wave in the channel
with a cross-sectional area equal
to twice the inlet cross-sectional
area. Assume steady,
one-dimensional isentropic flow
except through the normal shock
wave. Ax=2Ai , Ae=3Ai
