This:-
Deflagration and detonation are two ways energy may be released. If the combustion process propagates outward at subsonic speeds (slower than the speed of sound), it's a deflagration. If the explosion moves outward at supersonic speeds (faster than the speed of sound), it's a detonation.
I am pretty sure I mentioned supersonic in connection with detonation and that BP was not supersonic in post #35. Do I have to spoon feed that it is therefore subsonic? Was not your own statement of 900 - 950 f/sec not a clue? Had you read my post properly you would have understood it at the outset.
True freedom includes the freedom to make mistakes or do foolish things and bear the consequences.
