WebbThe equation for Darcy friction factor is given below, Hf = 4fLv2/2gD. Where, Hf = Pressure loss or head loss. f = Coefficient of friction factor or Coefficient of friction factor. L = Length of the coil or pipe. v = Velocity of the incompressible fluid. g = Acceleration due to gravity (value of g is 9.8 meter per square second) D = Diameter of ... WebbDarcy's Equation. The frictional head loss can be calculated using a mathematical relationship that is known as Darcy's equation for head loss. The equation takes two distinct forms. The first form of Darcy's equation determines the losses in the system associated with the length of the pipe. H f = f L D v 2 2 g.
