Question

Air flows in a duct, and a valve is quickly closed. A normal shock is observed to propagate back through the duct at a speed of 300 m/s. After the air has been brought to rest, its temperature and pressure are 500 K and 202 kPa, respectively. What were the original temperature, pressure and velocity of the air before the valve was closed?

Step 1

Step 1: Given information: - Shock wave speed, $V_s = 300 \, m/s$ - Temperature after the air is brought to rest, $T_2 = 500 \, K$ - Pressure after the air is brought to rest, $P_2 = 202 \, kPa = 202000 \, Pa$ We need to find the original temperature $T_1$, Show more…
