Compressible Flow Questions & Answers  
Please ask your questions related to Compressible Flow in this thread, I will answer them as soon as possible. To insert mathematics use . For instance, let's say we wish to insert math within a sentence such as $P$ is equal to $\rho R T$. This can be done by typing \$P\$ is equal to \$\rho R T\$. Or, if you wish to display an equation by itself out of a sentence such as: $$ \frac{P_\circ}{P}=\left( 1 + \frac{\gamma-1}{2} M^2 \right)^{\gamma/(\gamma-1)} $$ The latter can be accomplished by typing \$\$\frac{P_\circ}{P}=\left( 1 + \frac{\gamma-1}{2} M^2 \right)^{\gamma/(\gamma-1)} \$\$. You can learn more about on If the mathematics don't show up as they should in the text above, use the Chrome browser instead of Internet Explorer.

Sir , I have a doubt in understanding the slip line . Is slip line is like shear layer flow ? . And is it formed to make the flow to balance the pressure between the two shock wave's.
A shear layer is a viscous flow phenomenon. Here we are solving inviscid flow. In inviscid flow, the slip line is the boundary between two flow regions.
The two flow regions have the same pressure and their velocity vectors point in the same direction. However, the temperature, density, and the magnitude of the velocity may differ.

Hello Sir,
In Assignment 1, Question No.3, I am getting all the values correctly except the maximum attainable velocity by the gas. I am getting, \begin{equation} V_{2,max}=672.185\, m/s \end{equation} instead of $647\,m/s$ as given by you.
I assumed \begin{equation} M_{2}=1 \end{equation}and hence \begin{equation} V_{2,max}=\sqrt{\gamma R T} \end{equation} Sorry if I am wrong for your precious time.
But if $M_2=1$, then $T_2$ will have a different value than the one you computed..
