  • Every formula includes variable legend + SI/Imperial units.
  • Print-friendly (grayscale works fine) and screen-optimized with clickable table of contents.

    • When completing Module 3, an engineer should be able to answer:

    Problem: Size a carbon steel pipe for 100 m³/h of water at 60°C. Length = 500 m, 10 elbows (K=0.3 each), allowable ΔP = 2 bar. Every formula includes variable legend + SI/Imperial units

    Solution:

    Pressure rating: 60°C water, max operating pressure 10 barg → Design P = 11 barg. For CS ASTM A106 Gr B at 60°C, S = 138 MPa.
    Thickness: t = (11×168.3)/(2×138×1×1 + 0.4×11) ≈ 6.7 mm. Add 1.5 mm CA → 8.2 mm → Schedule 40 (7.11 mm? too low) → Use Schedule 80 (10.97 mm). Flanges: Class 150 suitable (19.6 barg @ 60°C). When completing Module 3, an engineer should be
