The Darcy-Weisbach equation is the fundamental equation for calculating pressure loss due to friction in pipes:
Where ΔP is pressure drop (Pa), f is Darcy friction factor (dimensionless), L is pipe length (m), D is pipe diameter (m), ρ is fluid density (kg/m³), and v is flow velocity (m/s).
Minor losses occur due to fittings, valves, and other components in the piping system:
Where K is the loss coefficient specific to each fitting type. The equivalent length method can also be used, where each fitting is converted to an equivalent length of straight pipe that would cause the same pressure drop.
