    Man my simple equation threw everybody off! It was simply the conservation of potential energy, P*Vbottle = m*g*h beer I chose the conservation formula to debate my buddy with because it's simple with no english/metric conversions (apparently too simple if we need to be working with the...

    Minimum C02 Pressure and Volume to tap a keg of beer

    Ivy- I've seen the 20 oz bottle lift the keg with my own eyes. These small bottle systems are found pretty commonly online. So the question is, Why is our math off by a factor of eight? (I miss-typed above - the math implies the bottle has enough energy to tap eight kegs! - the problem is I...

    Minimum C02 Pressure and Volume to tap a keg of beer

    Please help me settle a bet at work. How many kegs of beer can be pumped with a 20 oz. paintball CO2 tank? Assume pressure of CO2 tank is 1000 PSI, beer keg is 16 gallons (128 lbs), and lift to spout tap is 36 inches. Volume of paintball tank therefore is ~36 in^3. Using the potential energy...
