In theory if the resistance to the stuffing is higher, then it also pushes the air out harder - i.e. it's a wash.
Except that it's not, because when you compress air you heat it, and all the heat energy is gone. This is why compressed air is a terrible energy storage method.
The hotter you heat the air (higher PSI) the more energy you waste.
- function_seven 3y agoWouldn’t the air not be pushing against my piston? It’s already in the tank and the piston is being pushed by atmospheric pressure for the next gulp. Good note on the heat. I’ll wrap my whole setup in a blanket to recover that ;)
- raverbashing 3y agoIt does heat and you do lose some energy there, but not enough to lose all of the compression applied
