The formula to calculate the outside diameter of an O-Ring is:
\[ OD = ID + (2 \times CS) \]
Where:
An O-ring size refers to the dimensions of an O-ring, a mechanical gasket in the shape of a torus or doughnut. The size is typically defined by its internal diameter (ID) and its cross-sectional diameter (CS). These dimensions are crucial in ensuring a proper fit and effective seal in a variety of applications, such as in mechanical devices and plumbing systems, to prevent the escape or entry of gases or fluids.
Let's assume the following values:
Step 1: Multiply the cross-sectional diameter by 2:
\[ 2 \times 2 = 4 \]
Step 2: Add the result to the inside diameter:
\[ 20 + 4 = 24 \]
Therefore, the outside diameter of the O-Ring is 24 mm.
