How It Works

Calculate water flow and head loss using Hazen-Williams formula: V = 0.8492·C·R^0.63·S^0.54. C coefficients: new cast iron = 130, new steel = 140, PVC = 150, old cast iron = 80

Each component has a specific meaning:

  • Hazen-Williams formula: V = 0 — The hazen-williams formula: v = 0 recorded for the patient or scenario being assessed.

Note: Interpret the hazen-williams result against the clinical thresholds and context described above.

How to Use

Enter the Hazen-Williams formula: V = 0 for the patient or scenario you are assessing. Calculate water flow and head loss using Hazen-Williams formula: V = 0.8492·C·R^0.63·S^0.54. C coefficients: new cast iron = 130, new steel = 140, PVC = 150, old cast iron = 80. Use the hazen-williams result to inform your clinical assessment.
