Using the online calculators
No installation or account. Calculations stay in your browser; these tools neither send nor save your inputs.
Choose the right calculation
Open the tool matching your question. Check units: internal diameter in mm, pipe length in m and flow in L/h, except in the converter.
Adapt the examples
Replace prefilled values with your data, then select Calculate. Editing inputs clears the previous result: run the calculation again.
Read results with their assumptions
Read the formula and limitations alongside the result. No Windows installation is needed. For sizing or unknown data, speak with our team.
