gpfcalc is a GTK+ front-end for pfcalc, a pipe friction calculator using the Darcy-Weisbach equation. It computes major, minor, and static losses for flow through pipes or ducts. Up to 1024 pipes or ducts can be defined by specifying hydraulic diameter, length, roughness, flow rate, temperature, and elevation change. Data can be saved in a comma separated values file (CSV) and imported in the spreadsheet program of your choice for further processing.
