The pressure of a full acetylene cylinder can vary depending on the size of the cylinder and the temperature. Acetylene is typically stored in cylinders at a pressure of around 250 psi (pounds per square inch) at room temperature. However, this pressure can increase as the temperature rises, so it is important to follow safety guidelines and regulations when handling acetylene cylinders.

ProfessorOSHA standard, 1910.253(a)(2) says:
Maximum pressure. Under no condition shall acetylene be generated, piped
(except in approved cylinder manifolds) or utilized at a pressure in excess of 15
psig (103 kPa gauge pressure) or 30 psia (206 kPa absolute). ... This requirement
is not intended to apply to storage of acetylene dissolved in a suitable solvent in
cylinders manufactured and maintained according to U.S. Department of
Transportation requirements, or to acetylene for chemical use. The use of liquid
acetylene shall be prohibited.
The maximum safe working pressure with acetylene is 15 PSI, though most regulators and torches will cap flowrates well below this pressure. Because of the way acetylene is stored (high pressure, room temperature liquid form with small particles of balsa, charcoal, etc. in the tank) it requires time to absorb enough heat to allow some of the liquid to vaporize. If drawn too fast, you can either freeze your tank's valve, possibly damaging it dangerously, or draw liquid acetylene through your hose and have a big fiery mess right in your face as liquid acetylene hits the air and explosively evaporates and burns.
well gramaticly if the pressure of FUll or less depends on the gravity

How do you test a co2 cylinder?
Measure the weight of the full cylinder and note down as m1Note down the tare weight of the cylinder marked on the cylinder and note down t1the m1 - t1 = M the weight of gas in Kilogramsmultiply the wt of gas in Kgs with 0.9403 ie. M x 0.9403 gives the total cubic meter of acetylene gas in cylindersNote: One gram of Acetyle gas measures 0.9403 litres at 27 degree centigrade and 760 mm of mercury pressure.
How do you calculate diameter of hydraulic cylinder to create ton pressure?
The equation Force = pressure x surface of the cylinder Electric power and torque and power you need to know what you want. After obtaining the surface area of ​​the circle diameter cylinder, the cylinder can get.
Is a hydraulic jack a hydraulic or pneumatic system?
Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.
Can you use acetylene torch for silfoss?
no
How does the valve reservoir and pump function on a hydraulic cylinder jack?
the pump supply's the pressure, the resivoir supply's the fluid, the valve dirercts the fluid into the cylinder, to extend or retract the cylinder.
