How to Calculate and Solve for Burst Pressure | Polymer & Textile

Last Updated on March 9, 2024

The image above represents burst pressure. To calculate the burst pressure, three essential parameters are needed, and these parameters are tensile strength (T), half of outside diameter of tubing (x) and half of inside diameter of tubing (y).

The Formula for Calculating the Burst Pressure

P = ^{T(x² – y²)} / _{y²(1 + ^x²/y²)}

Where;

P = Burst Pressure
T = Tensile Strength
x = Half of Outside Diameter of Tubing
y = Half of Inside Diameter of Tubing

Let’s solve an example;
Find the burst pressure when the tensile strength is 12, the half of outside diameter of tubing is 11 and the half of inside diameter of tubing is 7.

This implies that;

T = Tensile Strength = 12
x = Half of Outside Diameter of Tubing = 11
y = Half of Inside Diameter of Tubing = 7

P = ^{T(x² – y²)} / _{y²(1 + ^x²/y²)}
P = ^{12(11² – 7²)} / _{7²(1 + ^11²/7²)}
So, P = ^{12(121 – 49)} / _{49(1 + ¹²¹/49)}
P = ¹²⁽⁷²⁾ / _{49(1 + 2.469)}
P = ⁸⁶⁴ / _49(3.469)
Then, P = ⁸⁶⁴ / ₁₇₀
P = 5.08

Therefore, the burst pressure is 5.08.
