Tube (fluid Conveyance) - Calculation of Strength

Calculation of Strength

For a tube of silicone rubber with a tensile strength of 10 MPa and a 8 mm outer diameter and 2 mm thick walls. The maximum pressure may be calculated as follows:

Outer diameter = 0.008
Wall thickness = 0.002
Tensile strength = 10 * 1000000
Pressure burst = (Tensile strength * Wall thickness * 2 / (10 * Outer diameter) ) * 10

Gives burst pressure of 5 MPa.

Using a safety factor:

Pressure max = (Tensile strength * Wall thickness * 2 / (10 * Outer diameter) ) * 10 / Safety_factor

    “To my thinking” boomed the Professor, begging the question as usual, “the greatest triumph of the human mind was the calculation of Neptune from the observed vagaries of the orbit of Uranus.”
    “And yours,” said the P.B.
    Samuel Beckett (1906–1989)

    Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation appled to life.
    Henri-Frédéric Amiel (1821–1881)

    We meet I don’t say when
    But must bring to the meeting the maturest,
    The longest-saved-up, raciest, localest
    We have strength of reserve in us to bring.
    Robert Frost (1874–1963)
