Question
Darcy Weisbach equation is used to find loss of head due to -
The correct answer is
Friction
This loss occurs primarily because of viscous shear stresses within the fluid and between the fluid and the pipe wall, which we commonly refer to as friction. The Darcy-Weisbach equation for head loss due to friction is given by: h_f = f (L)/(D) (V^2)/(2g) Where: h_f is the head loss due to friction (usually in meters or feet).
