2. Shock-Tube Testing Time
3. The final results are applicable also to a square tube of sided, since the ratio of cross-sectional to wetted area is the same as for the circular one.
4. In this statement we are neglecting the fact that the temperature loading (Te−Twire) decreases as the wire temperature rises; for strong shocks the wire heats up to only a fraction of its equilibrium value Te, and thus the heat transfer rate is practically constant.
