<font size="2" face="Verdana, Arial">100% right. focused one would be right if we were trying to suck up water, in that it would be harder through a straw with a hole. But, we're trying to suck up air like machine said. If anything it would help.Originally posted by Machine:
gonna have to disagree with that one. the reverse cone increases filter area this always increases flow. a straw with a hole in it flows more air because there is more hole.
suck through one straw,
add another straw, which increases "hole" area
and suck more air.
if you relate it to sucking fluid, then the hole in the straw must be submurged in the liquid. you would suck more liquid.
fluid dynamics and gas dynamics are seperate disiplines and to properly measure flow you cannot introduce the other.
