Constant entropy flow is called Isentropic flow.

From a consideration of the second law of thermodynamics, a reversible flow maintains a constant value of entropy

Below are the formulas... someone needs to add some explaining text here

M = \frac{u}{a}

a = \sqrt{\gamma R T}

\frac{p_0}{p} = (\frac{T_0}{T})^\frac{\gamma}{\gamma - 1}

\frac{p_0}{p}=(1+\frac{\gamma-1}{2}M^2)^{\frac{\gamma}{\gamma-1}}

\frac{T_0}{T}=1+\frac{\gamma-1}{2}M^2

\frac{\rho_0}{\rho}=(1+\frac{\gamma-1}{2}M^2)^{\frac{1}{\gamma-1}}

\frac{A}{A*}=\frac{1}{M}*(\frac{\gamma+1}{2})^{\frac{-\gamma+1}{2(\gamma-1)}}*(1+\frac{\gamma-1}{2}M^2)^{\frac{\gamma+1}{2(\gamma-1)}}
