A normal shock process can be interpreted as the simultaneous satisfaction of Fanno and Rayleigh

conditions. Then, consider Air at $300$ K and $1\mathrm{.}5$ MPa travels at a Mach number of $2\mathrm{.}5$ just before it is

decelerated by a shock wave. Setting the entropy of the air equal to zero at this initial condition, draw the

Rayleigh and Fanno lines that pass through this initial state point in a T$-$s diagram. Also, show that a point

of second intersection of these Rayleigh and Fanno lines represent the state of the air immediately

downstream of the shockwave. $($Refer to Textbook problem $3\mathrm{.}10$ Explain and solve it detaily please
