The circular cross-section is the concentric circle of the pipe. It can be calculated by using the diameter values or the ratio values.

How to calculate the circular cross-section of a pipe?

When talking about circular cross-sections we are referring to the concentric circle resulting from the intersection between the pipe and a plane.

To calculate the cross-section area, Ac, we need to know either the values of the diameters or the ratios.

  • the values of the inner and outer diameters, D and d.

The formula to calculate it is Ac = π * (D² - d²) / 4

  • the inner and outer ratio values r, r1 and r2.

The formula is  Ac = π * (r₁² - r₂²)

According to the provided information in your problem statement, use any of these formulas to calculate the circular cross-section of the deep water horizon pipe.
