pfcalc stands for pipe friction calculator and is a CLI program that computes pressure drop in piping systems using the Darcy-Weisbach equation. There are two front-ends available for pfcalc: gpfcalc is a Gtk front-end and Qpfcalc is a Qt front-end.
The program is capable of computing minor and major pressure losses (pipe friction losses) for flow in pipes and ducts. It serves as a free software replacement for similar proprietary software programs. The intended user base is made of those people working in the fields of mechanical and civil engineering, who need to estimate pressure drop in new or existing piping systems.
Data can be fed through command line arguments or can be read from a comma separated values file (csv). This is a text file that contains values separated by commas and can be exported from various spreadsheet programs. Every line is a data set that contains the following values, in this order: diameter, length, roughness, elevation, flow-rate, minor loss coefficient (K-factor), temperature. The program will read the file, make a calculation for every data set and print the result. Calculation results can be exported to a csv file that will contain a result per line, with values in this order: diameter, length, roughness, flow, temperature, velocity, Reynolds number, Darcy factor, hydrostatic pressure loss, minor pressure loss, major pressure loss.
