Important Notice

This calculator is provided for educational and informational purposes only. Professional engineering decisions should always be verified through multiple sources and qualified professionals.

Educational Purpose

The Moody Chart Calculator is designed as an educational tool to help students, engineers, and researchers understand friction factor calculations and the Moody diagram. While based on established fluid mechanics principles and the Colebrook-White equation, this tool should not be the sole basis for critical engineering decisions.

Accuracy and Limitations

Calculation Accuracy

  • Results are based on standard fluid mechanics equations and numerical methods
  • Calculations assume steady, incompressible flow of Newtonian fluids
  • Iterative solutions use convergence tolerances appropriate for most applications
  • Results may have minor variations compared to other calculation methods

Scope Limitations

  • Valid for circular pipe flow only
  • Does not account for entrance effects, fittings, or valves
  • Assumes uniform pipe roughness and fully developed flow
  • May not be suitable for non-Newtonian fluids or compressible flow
  • Does not consider temperature or pressure effects on fluid properties

Professional Responsibility

Engineering Applications

For professional engineering applications, users should:

  • Verify results using alternative calculation methods
  • Consult relevant engineering standards and codes
  • Consider safety factors appropriate for the application
  • Have calculations reviewed by qualified professionals
  • Account for real-world conditions not modeled by this tool

Critical Systems

This calculator should NOT be used as the primary calculation method for:

  • Safety-critical systems where failure could result in injury or death
  • High-value industrial processes without additional verification
  • Regulatory submissions or permit applications
  • Final design calculations for constructed systems

No Warranty

This software is provided "as is" without warranty of any kind, either express or implied, including but not limited to the implied warranties of merchantability and fitness for a particular purpose. The entire risk as to the quality and performance of the program is with you.

Limitation of Liability

User Responsibility

By using this calculator, you acknowledge and agree that:

  • You understand the limitations and appropriate use of this tool
  • You will verify results through independent means for critical applications
  • You assume full responsibility for any decisions based on these calculations
  • You will not hold the creators liable for any consequences of using this tool

Recommended Resources
