what are the regulations for transporting small nitrogen cylinders?

Contact the state Department of Transportation for information on what restriction exists for the road of your state.

liquids and gases only.\nparticles must be able to move around to form convection currents and solid particles are not free to move about.

Absolutely,it is okay!The cylinders are designed to hold thousands of pounds of pressure,regardless of ambient temperature.Also if you look close on the cylinder neck at the shut off valve,you will see a blow off port ,it is permanently there for over pressure blow-off but the summer heat makes little difference.WHAT TO WATCH FOR-have no oil near the tank ,when mixed oxygen there will be an explosion!Do not drop tank.the end could rupture and it will take off like a missile.Also no smoking ,I am not sure why but I have always heard that .

Yes, the answer is h = 2r\n\nThis is a classic optimization problem. You want the minimum surface area(SA) for a cylindrical shaped tin for a fixed Volume(V)\n\n(1) SA = 2pi r^2 + 2pi r h\n\nV = pi r^2 h (for simplicity set V = 1)\n\nso (2)    h = 1/(pi r^2)\n\nSubstituting this value for h into (1) gives:\n\nSA = 2pi r^2 + 2/r\n\nd/dr SA = 4pi r - 2/r^2\n\nd/dr SA = 0 when 2/r^2 = 4pi r\n\nthat is: (3)   r = 1/(2 pi r^2)\n\nTo get the value of the ratio h/r divide equation (2) by equation (3), which yields a value of 2 to 1.\n\nh = 2r

Lecture bottles are very small compressed gas cylinders, typically 2-3 inches in diameter and 12-18 inches in height. They are used to deliver small quantities of compressed gas, generally to science labs. I don't know where it got the name, but maybe the small size was used for science demonstrations during science class lectures?

You are already stressing the components of the motor by almost doubling the cubic centimeters and in my opinion adding the extra horsepower of nitrous to a motor that wasn't ment for it would cause blown head gaskets, overheating and piston melt down. Those motors are touchy enough without the nitrous!

Ack... Munir got here before I did agian.  A agree with Munir!  Volume of any gas at STP is 22.4L.

I would suggest contacting the manufacturer (or CO2 supplier) then consider whether your application is more or less critical and thus may be covered by industry codes.  There is high pressure and then there is high pressure and your specific pressure, environment and use (pressure cycles?) may be important.  If there were an accident or interruption of CO2 service, you might be liable for not following codes or using good judgement (backed up by your formal contacts?).  Also, can the CO2 supplier furnish you with tested cylinders to avoid contaminating them with hydro fluid?

Its available. R-12 & R-22 are restricted by the EPA and being phased out.

Its not a nationwide law, its specifc to the state and even to the municipality.  In New Orleans, they are very liberal with regard to walking around on the street with an open container.  In NYC, you can't do that, you'll get a ticket.

It depends on how it's used, but common uses of Nitrogen... It's part of a compound in fertilizers, it's used to freeze things, it's used to fill up tires, it's used in cars for more power, those are just a couple, I am sure there are thousands more that I don't know of.

All materials shipped anywhere in the world will have a set of documentation appended. EIther it will be internal to a country, in which case the document could list what the substance is called locally, or it could be traveling internationally, in which case it must have a United Nations Identification Number.\n\n316 SS UN refers to the material known internationally as "stainless steel, grade 316".

You probably need more information...there can be multiple cylinders inscribed in a sphere with a radius of 5.
