I need to know the maximum compression speed that can be applied to a rectangular bladder which has a open air port that will avoid rupturing the bladder. The bladder is 40" wide, 100" long, and 10" tall. The compression equipment is a large metal panel that is larger than the surface area of the bladder. The material inside the bladder is air. The port has an internal diameter of 0.50" and is a rigid material. The bladder has a maximum internal psi capacity of 0.5psi to avoid ruptures. Ignoring the flexing of the bladder material, is there a way to calculate this rate of compression that I could achieve while not rupturing the bladder? Thank you.
