Why does pop fizzy?
pop is fizzy because co2 prolongs the life of pop, before pop is made, treated water it is evacuated of all oxygen particles then blasted with co2 at around 6bar (87psi). this water is then mixed with syrup (like a cordial) at about 2.5 parts of water to 1 part of syrup (depends on type of pop eg. diet, energy, cola etc....) it is the sent through a filler into a can. it is actually more complicated then that but that's it in a quick lesson also not all pop is fizzy it can be filled using nitrogen these are typically fruit drinks...

How to Convert kg's of air to cubic meters of air at 6bar?
Air at 10 celsius and 1 bar(absolute) has density 1.25 kg/m3. By 6 bar do you mean gauge or absolute pressure? To apply a pressure factor you must use absolute, ie the pressure above a vacuum. Normal atmospheric conditions are 1 bar (abs). If you mean 6 bar(abs) the density becomes 6 x 1.25 = 7.5 kg/m3. On the other hand if you mean 6 bar (gauge) this is 7 bar (abs) and the density would be 7 x 1.25 =8.75 kg/m3. Either way, you just divide the weight of air in kg by the density to get the volume.
do you know is it suitable to transfer gas with plastic pipes could anyone solve my questions?
as my former working experience at RIIFO, I know that RIIFO has a set that are especially for transfering gas-PAP and PEX tubing with F5 fittings. As I learned that gasoline transportation can be done with PAP or PEX pipes, and it’s OK to connect F5 fittings. But gasoline corrosion resistance of PEX is grade C, which implies that at 80℃, the maximum operating pressure does not exceed 60% of the working pressure, that is, the design working pressure is 6bar, and the maximum gasoline transmission pressure is 3.6 bar. Both PE/AL/PE or PEX/AL/PEX pipes can be in contact with LPG for a long time. The melting point of PE is 125℃, and PEX does not melt. So I think the answer is YES!
