fluids

A Python library with hundreds of functions for engineering fluid mechanics. It covers friction factors and pipe roughness, pressure drop in fittings, pump and motor sizing, compressible and two-phase flow, open-channel flow, tanks, orifice plates and Venturi meters, control and relief valves, packed beds and atmospheric properties. It suits process, mechanical and piping engineers who want transparent calculation sheets in code instead of Excel. There is no graphical interface.
