Introduction. The 3K method allows the user to characterise the pressure loss for flow through fittings in a pipe. As the name suggests, three K coefficients are used to characterise the fitting, which when combined with the flow conditions and the pipe diameter may be used to calculate the fitting K value.Once the K value has been determined the head or pressure loss through the fitting may pipe fitting resistance coefficient in norwayPressure Loss from Fittings - Excess Head (K) Method pipe fitting resistance coefficient in norwaySummary.

For all pipe fittings it is found that the losses are close to being proportional to the second term in Equation (1). This term (v 2 /2g) is known as the "velocity head". Both the equivalent length (L e /D) and the resistance coefficient (K) method are therefore aimed at Pressure loss in pipe systems (Darcy friction factor pipe fitting resistance coefficient in norwayWith a pipe diameter of \(d\) = 1 cm, a minor loss coefficient of \(\zeta=1\) and a friction factor of \(f\) = 0.02, an equivalent pipe length of only 0.5 m is obtained. With very long piping systems and only few individual components (which is often the case), the pressure loss due to the installed components can therefore usually be neglected.Resistance Coefficient Method K MethodResistance Coefficient Method K Method. The resistance coefficient method (or K-method, or Excess head method) allows the user to describe the pressure loss through an elbow or a fitting by a dimensionless number K.This dimensionless number (K) can be incorporated into the Darcy-Weisbach equation in a very similar way to the equivalent length method.
