Question

how to convert ?
6L (nitrogen) at 2500psig would equal how many L at 0psig?

Answer 1

I have no idea what any of this means btw :P
my dad needs to know for work or something...

Answer 2

@wio could you help pwease? :3

Answer 3

Sorry, I have no idea about this, wish I could help. :D

Answer 5

pounds per square inch... 0.o

Answer 6

Nice music on Soundcloud too :D

Answer 7

thanks :)

Answer 8

Oh okay, my pleasure, what is your dad trying to measure?

Answer 9

idk
I think he has compressed nitrogen in a tank and he want to know the volume of it at normal pressure...

Answer 10

Oh okay, good luck with your dad on that.

Answer 11

lol thanks ^_^

Answer 12

:D Any time

Answer 13

Answer 15

@Mertsj if you're not too busy, could you help? or if you don't know either, could you tag someone that might know how to help me?

Answer 16

I think you want the gas law:
\[P _{1}V _{1}=P _{2}V _{2}\]

Answer 17

ok, thanks! :)

Answer 18

would it be 1011.708 L then?

Answer 19

idk cuz normal pressure for psig is 0 right?

Answer 20

Here comes the cavalry

Answer 21

Since you can't divide by 0, it's likely you'll need to convert psig.

Answer 22

at sea level, the atmospheric pressure is 14.7 psi. he's got a psig reading, which doesn't account for the sea level pressure — so his actual pressure is 2500 psi + 14.7 psi.

\[P_1 = 2514.7\]\[V_1=6\]\[P_2=14.7\]\[P_1V_1 = P_2V_2\]\[V_2=\frac{P_1V_1}{P_2} = \frac{2514.7*6}{14.7} = 1026.4 \]

Answer 23

ohhh okay, got it now! :)
thanks! :D

Answer 24

This answer comes with no warranty of suitability for filling breathing tanks, hot air balloons, high pressure boilers, etc. :-)

Answer 25

lol my dad's reaction:
"ok, so 1026.4L in 46 hours would be about 22L
then two machines using it... so about 11L per machine per hour...
0.o that can be right...
... *** there must be a leak then... "
