where D H is the duct hydraulic diameter. The total energy equation becomes an equation of total enthalpy conservation. The equation reads:

In differential form:

By replacing C p = γR∕(γ − 1) we find:

what leads to

(2.68)

Using the definition of the Mach number, we write:

In differential form:

Dividing the last equation by u 2, we have:
