Enter flow rate (100 GPM).

Select "Water" or "Standard Fluid" from the fluid library. Input length (200 ft) and elevation change (if any)

Remember: The accuracy of the output depends entirely on the quality of the input. Always verify fluid properties, pipe inner diameters, and roughness values. Use the calculator as a design tool, not a black box. And for mission-critical systems (e.g., high-pressure steam or toxic chemicals), always perform a sanity check via manual approximation or a second calculation method. Remember: The accuracy of the output depends entirely

Add fittings. Click "Elbow 90° LR" x 4, "Gate valve (full open)" x 1. The calculator sums the K-factors or uses the equivalent length method.

Choose pipe material – "Carbon Steel" – and select "2 in Schedule 40". The calculator automatically pulls the inner diameter (2.067 inches) and roughness (0.0018 ft or 0.045 mm).
