[QUOTE="audioholic, post: 989525, member: 549629"] After reading the ECA thread a bit more carefully, I understand where werewolf was going with that. The key equation difference is indeed box volume, and his equation does explain my error. Enclosure volume does indeed change. When the cone moves in, enclosure volume drops. When the cone excurts out, enclosure volume rises. The number of air molecules does not change (in a sealed system at least), but the volume size does, even if slightly. Thanks for the info squeak, I should have thought of that myself. [IMG]//content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif[/IMG] [/QUOTE]
