A test in a shock tube measures a pressure ratio across the shock of p_2 - p_1 = 50.0. The undisturbed air upstream of the shock is at 290 K and 10 kPa, and the driven section of the shock tube is 10 m long.

FIND:

What is the shock speed and what are the temperature and pressure downstream of the shock? How much test time do you get before the shock reflects off the end of the tube?

Solution

The stock speed is 25m/s.

The temprarure andpressure are 313 k and tunas

The required test time is 34min and45seconds.
