Even with today's computers a simplified method can reduce the tedious
work involved in computational work.
In particular, the trends can be examined with analytical methods.
It further will be used in the book to examine trends in derived
models.
It can be noticed that the Mach number involved in the above
equations is in a square power.
Hence, if an acceptable error is of about %1 then will result in the same fashion The pressure difference normalized by the velocity (kinetic energy) as correction factor is From the above equation, it can be observed that the correction factor approaches zero when ![]() The definition of the star Mach is ratio of the velocity and star speed of sound at M=1.
The normalized mass rate becomes The ratio of the area to star area is
