Sf Pressure: Drop Online-calculator

Enter flow rate (100 GPM).

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. sf pressure drop online-calculator

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. Enter flow rate (100 GPM)

Input length (200 ft) and elevation change (if any). For horizontal runs, elevation is zero. Use the calculator as a design tool, not a black box

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).

Enter the temperature (45°F). The calculator auto-fills density (62.4 lb/ft³) and viscosity (1.3 cP – slightly higher than room temp).
