What is the internal deflagration pressure for an H2 system?

The deflagration pressure is dependent upon many variables.

However, some general concepts are:

1. Deflagration pressure is proportional to operating pressure
2. Deflagration pressure is inversely related to initial temperature
3. Deflagration pressure is based on concentration and H2/O2 ratio
4. In general, an internal deflagration is unlikely to exceed about a 10:1 pressure ratio and an internal detonation pressure is unlikely to exceed 20:1.
