WebThis reduction in pressure due to friction between the flowing fluid and solid wall is commonly known as head loss. The engineering designs of such piping networks are mainly done using the head loss coefficient ( K) also known as K -factor. The head loss coefficient ( K) in various pipe fittings is predicted using Equation (2) . WebThe 3 methods which are used to calculate the minor losses in pipe sizing exercises are the equivalent length (L e /D), the resistance coefficient (K) and the valve flow coefficient (C v ), although the C v method is almost exclusively used for valves.
