which is flying at 800 km/hour through still air having a pressure 8.0 N/cm2 (abs) and temperature -100 C. Take R=287 L/g K and k =1.4

Given :

$$ \begin{array} \text{V} =800 {Km}/{P h} &=\frac{800 \times 1000}{60 \times 60} \\ &= 222.22 {m} / {s} \\ \text {Pressure of a air }\left(P_{1}\right) &=8 {N} /{cm}^{2} \\&=8 \times 10^{4} {N} / {m}^{2} \\ T =100^{\circ}{C} &=100+273=373 {K} \\ K &=1.4\\ \end{array} $$

Now for Adiabatic process,

The …
