  • What is the formula to calculate the OD of a pipe after 12 inches?

  • OD = 14 × 25.4
  • OD = (pipe size × 25.4) (correct)
  • OD = (pipe size + 2) × 25.4
  • OD = 12 × 25.4

    Study Notes

    Pipe Measurement System

    • The system that measures pipe size in inches is referred to as the "Imperial system" or "Inch-based system."

    Abbreviation in Pipe Standards

    • 'XS' stands for "Extra Strong," indicating a pipe with greater wall thickness compared to standard pipe categories.

    Calculating OD of a Pipe

    • The formula to calculate the Outer Diameter (OD) of a pipe after 12 inches involves adding twice the wall thickness to the nominal pipe size.

    Effect of Increased Thickness

    • When the wall thickness of a pipe increases, the Inner Diameter (ID) of the pipe decreases proportionally, affecting its flow capacity.

    Calculating CF of a Pipe

    • The formula to calculate the Capacity Factor (CF) of a pipe can involve the flow rate and internal diameter, typically expressed as CF = Flow Rate / (ID)^2, reflecting the relationship between diameter and flow.
