Air has a velocity of 1000 km/hr at a pressure of $9.81 KN/m^2$ vacuum and a temperature of $47^0C$. Compute the stagnation properties (Pressure, Temperature and Density). Take atm pressure $98. 1 KN/m^2, R =287 J/Kg^0K$ and $\gamma = 1.4$

Velocity of air,

$V_0\ =\ 1000\ km/hr\ =\ \frac{1000\ \times 1000}{60\ \times 60} \ = 277.78\ m/s$

Temperature of air,

$T_0\ =\ 47\ +\ 273\ =\ 320\ K$

Atmospheric pressure,

$p_{atm} = 98.1 \;kN/m^2$

Pressure of air (static),

$p_0 = 98.1 -9.81=88.29 \;kN/m^2 \\ R=287 \;J/kg \;K \\ γ = …
