Darcy friction factor 뜻
WebThe Darcy friction factor, fD, is a component of the Darcy-Weisbach equation, used to describe head loss due to friction. Calculating the Darcy friction factor involves the … WebFrictional loss is that part of the total head loss that occurs as the fluid flows through straight pipes. The head loss for fluid flow is directly proportional to the length of pipe, the square of the fluid velocity, and a term accounting for fluid friction called the friction factor.
