nitrogen question

[paintball_kid03]

what tank would u recommend for bushmasters (output pressure, size, etc.) would 48 ci, 3000psi, 850-900 output work

[Mack Daddy420]

Yes, it would work.

[chadthedude]

wouldnt a preset of 400-450 work a lot more efficent?

[Mack Daddy420]

Yes. The BKO isnt suppose to take any more than 300psi into its solenoid, Im assuming he has a gauge and reg.

[paintball_kid03]

Im buying a nonLCD b2k2 and im trying to plan ahead and trying to figure out how much i will be spending. What do you guys use when it comes to tanks, or what is suggested.

[Casper1ns]

on a b2k get a 45/4500 crossfire and on a bko i would go with a 48/3000

[PJGEM]

Yes. The BKO isnt suppose to take any more than 300psi into its solenoid, Im assuming he has a gauge and reg.

Thats why there are 2 regs. the hpr reg to deal with the high input from a high (850psi) tank. The hpr reg turns the pressure down to 220-250( whatever you make it ) and then the Lpr takes the 220-25- psi and turns it close to 90 psi( turn lpr till cycles then turn it more fo rabout one whole turn)
this is the autococker way in which lower is better

this whole process is explained in many areas on this board.

it all depends on the position you want to play, for front, its all about the pop cans, (45,4500) for the back i would recomend something like a 68, 4500 or even an 88, 4500 but you would need a really big drop.

How many shots can you get out of a 45ci. 4500psi. tank

[bsucaptainbilly]

hey, it is almost impossible to determine the exact number of shots that you need but i will give it my best shot,

ok we start with the formula

{[(psi)-(operating pressure)]/(14.7) }* (ci) = amount of usable air

now i'll explain it

first you take the psi of the tank, say that it is a 3000 psi tank. then you subtract the pressure that is required to cycle the gun and give a full velocity shot. For a bushy i am going to guess at around 500 psi going into the HPR.

so you take 3000 psi minus 500 psi. that leaves you with 2500 psi of usable pressure. then you want to convert it to units of atmospheric pressure. so you divide it buy 14.7 (the atmospheric pressure at sea level) and that leaves you with 170.07 (about) times the normal atmospheric pressure, or 170.07 bar.

then you multiply 170.07 by the volume of air in the tank, in this case we'll say that it is a 68 ci tank. so 170.07 times 68 is 11,564.76

so it would take a bag that was 11564.76 cubic inches to hold all the usable air for your marker.

now i'll do a pop can (45/4500)

so i use my formula, i'm not gonna show you the steps. If ur still unsure send me a privat message.

12,244.898

so it would a bag of 12,244.898 cubic inches to hold all the usable are in a pop can.

you can't really chech this to find out how many shots, but you could call ICD and ask them how much air at what pressure it takes going into the HPR to make a full velocity shot, then take the number you got from this formula, and divide it by that number you get from doing the following w/ the numbers that ICD gives you:

[(psi)/14.7] * ci

p.s.

i got this information and modified it a little from the April 2003 edition of APG, i know it's not april yet, but i got this issue in febuary in the mail. they are way ahead.

Youre clueless

[bsucaptainbilly]

ok dude, apperantly you don't know how to do math, this is the best way to do this w/ out going to buy a tank and testing it. (i do think that testing it w/ a real tank is the best way)
