This equation will not be used inside region I, because
the mixing zone represents such a small region that an
error in the total enthalpy there can have little ef-
fect on the overall energy balance. However this
equation is used in the other regions in order to
determine the flow centerline density eL and velocity
U. to be used in the density and velocity profiles.
Integrate the equations by substituting the proper
velocity profile functions ~.( * ; FI') *? 4
For the shear stress one has to insert the proper
function of the velocity and its first and second
derivative on the dividing streamline. The temper-
ature effect is given by the local density es

The wall shear stress is given by a friction coefficient
based on the local Reynolds number
