    Tanks

    Sorry, I'm not sure where to post something like this, but lets try here -
    what would be the price of a used Dye 70/45 stubby? For example how much would one with hydro in 2012 be? or 2013?
    Thank you.

    Yeah they are. stubbies are usually good if u r front tho cuz of the capacity of the tank. but yeah they are good tanks

    whats the difference between 68/45 and a 70/45? is it that much of a difference?

    the 70/4500 is physically smaller than the 68/4500 though.

    Actually the 70/45 has a larger volume then the 68/45. It's "smaller" in that its shorter, but it makes up for it in being fatter as it's width is greater. The 68/45 appears to be "larger" in that its length is longer and its width is shorter. That's why there's a difference in size, but each tank either makes up for shorter length in a wider width, or longer length for a shorter width.

    Just my 2 cents, correct me if I'm wrong.

    Makes sense, and now we may be getting into logistics, but do they not both hold 4500 psi of air? cause thats what the gauge is, which doesnt make sense because it is 70 cu inches. so this is where i am lost. I'm looking for the one that can old the most air, I dont care about size.

    Well 4500 psi is the pounder per square inch that the air inside exerts on the cylinder. It's the cubic inches that determine the volume of air that can be held. So in short, if your looking for a tank that hold the most air, get the one with the biggest cubic inches. I've heard of some that range in the 90's haha, but those are quite chunky.

    Oh alright, but then why are gauges in psi? I feel lik a noob.

    Well the gauges are used to show the pressure that the air inside is under. Each shot you take requires a certain volume, and pressure of air. So as you use up the air the pressure gradually decreases.

    But lets say when your filling up your tank, it doesnt show that there is a difference in air used between the 68 and 70/4500 - is this cause its supposed to be common sense, or for other reasons.

    At PAG, when you go to fill up your air tank, the gauge reads "psi * 1000" or what not. This meaning it will fill the tank to it reaches 4.5 on the gauge. Why does it not say Cu INCHES filled? cause the 68/4500 and 70/4500 both hold 4500 psi.

    Well I mean technically the tank in cubic inches is already "full" in that there is already air inside, if there wasn't it'd create a vacuum and essentially collapse on itself. The gauge reads the pressure because thats essentially what your doing, your adding more pressure to the tank by adding more air into it.

    Thats the general process I believe.

    You're looking at this from the wrong angle. How much air a tank holds is determined by both the volume and pressure.

    At atmospheric pressure, a 68ci tank will hold 68 cubic inches while a 70ci tank will hold 70. When you start filling them, the same amount of air will end up being less pressure in the 70 cubic inch due to the higher volume, but when both are filled to 4500psi, the higher volume tank holds more air. To get an accurate volume of air, you need both the volume of the tank and pressure combined.
