WebDarcy–Weisbach equation. In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach. WebThe K value may be converted into head loss through multiplication with the fluid velocity head as shown in the equation below. \displaystyle h_ {L}=K\frac {V^ {2}} {2g} hL = K 2gV 2. Some methods require the friction factor to be known of the pipe. For full details of the method of calculating the friction factor see pressure loss from pipe.
